Butyrfentanyl is a synthetic opioid compound and structural analogue of fentanyl, designed primarily for receptor-binding research and forensic analysis. It is not approved for medical use in humans or animals. Due to its high affinity for the µ-opioid receptor, Butyrfentanyl is commonly studied in the context of potency comparisons, toxicology models, and synthetic opioid pharmacology.

• Synthetic Opioid Analogue
  Butyrfentanyl mimics the structure of fentanyl with a butyryl group substitution, which influences its binding profile and receptor interaction, especially at the µ-opioid receptor (MOR).

• Pharmacological Tool for Research
  It is widely used in scientific studies to understand opioid receptor dynamics, receptor affinity modulation, and cross-reactivity with endogenous peptides.

• Short-Acting Potency Profile
  Compared to fentanyl, Butyrfentanyl exhibits lower potency and a shorter duration of action, which makes it useful for research scenarios that require fast receptor turnover or acute-dose modeling.

• No Approved Human Use
  Butyrfentanyl has no clinical or veterinary approval. Its use outside of controlled lab conditions can result in severe toxicity or death, primarily due to respiratory depression.

• Used in Toxicological and Forensic Studies
  Laboratories frequently include Butyrfentanyl in panels for screening unknown synthetic opioids during forensic toxicology analysis, particularly in post-mortem cases or seized substance evaluations.

The legal status of Butyrfentanyl varies significantly by country and is typically subject to strict regulations due to its structural similarity to fentanyl and its pharmacological activity. Researchers must be aware of their local laws before attempting to acquire or handle this compound.

• Controlled Substance in Multiple Countries
  In the United States, Butyrfentanyl is classified as a Schedule I substance, making it illegal to possess outside of a DEA-licensed facility. The UK, Canada, and much of the EU have also moved to control this compound under their national drug laws.

• Research-Only Classification in Some Regions
  Certain countries do not specifically name Butyrfentanyl in their controlled substance lists, allowing it to be legally used for non-human, academic, or forensic research when ordered by authorized institutions.

• Import/Export Regulations Apply
  Even in research-approved regions, Butyrfentanyl may be restricted by customs or import control agencies. A proper research declaration or lab authorization may be required.

• End-User Responsibility
  Buyers are solely responsible for ensuring compliance with applicable laws in their region. At RC Plug, we only sell Butyrfentanyl for research purposes, and purchasers must affirm they meet legal requirements.

• Documentation Support Available
  We provide supporting documentation such as Safety Data Sheets (SDS) and Certificates of Analysis (COA) to assist with customs or regulatory inquiries during shipping.

Butyrfentanyl is valued in chemical and pharmacological research due to its structural and functional relationship to fentanyl. Its primary applications revolve around opioid receptor studies, analytical standard development, and toxicological screening models.

• Receptor Binding Assays
  Butyrfentanyl is used in in vitro experiments to assess binding affinity and efficacy at the µ-opioid receptor, enabling comparison with other analogues and ligands.

• Potency Benchmarking in Drug Discovery
  It serves as a potency control or comparative agent in the development of new opioid derivatives or antagonists, especially those intended to reverse synthetic opioid effects.

• Analytical Standard in Toxicology
  Accredited forensic and toxicology laboratories utilize Butyrfentanyl as a reference material for identifying and quantifying synthetic opioids in biological specimens.

• Pharmacokinetic Modeling
  Researchers study Butyrfentanyl’s metabolism, onset, and elimination to model how structural modifications influence pharmacokinetics among opioid analogues.

• Cross-Reactivity Testing
  Butyrfentanyl is used to assess how opioid receptor antagonists (like naloxone) respond to different synthetic opioids, supporting the development of more robust overdose-reversal treatments.

Butyrfentanyl is significantly less potent than fentanyl but still exhibits several times the potency of morphine. Its potency profile is a key focus in opioid pharmacology and receptor-binding studies.

• Approximately 7 Times Stronger Than Morphine
  Although estimates can vary depending on the model, Butyrfentanyl is widely considered to be about 5–7 times more potent than morphine in terms of µ-opioid receptor activation.

• Roughly 10–15 Times Less Potent Than Fentanyl
  Fentanyl is 100–120 times stronger than morphine, meaning Butyrfentanyl is significantly milder, making it safer to work with under controlled conditions for research.

• Short Duration of Action
  Butyrfentanyl has a relatively brief active window (2–4 hours), allowing for short-term studies that do not require extended receptor occupancy.

• Useful for Acute Receptor Studies
  Its intermediate potency makes it ideal for studies that aim to observe opioid receptor response without overwhelming receptor saturation, which is common with fentanyl analogues.

• Ideal for Comparative Pharmacology
  Researchers use Butyrfentanyl alongside analogues like acetylfentanyl and valerylfentanyl to understand how different substitutions affect potency and receptor interaction.

Proper storage of Butyrfentanyl is essential for preserving its chemical integrity, purity, and usability over time. Exposure to incorrect conditions can degrade the compound and compromise research results.

• Store in a Cool, Dry Place
  Butyrfentanyl should be kept at room temperature (15–25°C) in a dry environment, away from humidity and temperature fluctuations.

• Protect from Light and Air
  Store in an opaque, airtight container to prevent degradation from light exposure and oxidative reactions. UV radiation and air can alter its molecular structure over time.

• Use Vacuum-Sealed Containers for Long-Term Storage
  For prolonged storage, vacuum-sealing is highly recommended. It prevents moisture ingress and maintains stability over months or years.

• Avoid Freezing Unless Specified
  Freezing is not typically required, and repeated freeze-thaw cycles can lead to condensation inside the container, affecting the compound.

• Label and Secure Storage Area
  Clearly mark containers as “Research Use Only,” and store them in a restricted-access location in accordance with institutional safety protocols.

• Check for Clumping or Color Changes
  Before each use, examine the sample for clumping, discoloration, or odor changes, which may indicate contamination or degradation.

Butyrfentanyl is strictly prohibited for human or animal consumption. It is not an approved pharmaceutical and poses significant health risks outside of a controlled laboratory setting. Its use must be limited to research activities carried out by trained professionals in accredited facilities.

• Not Approved by Any Health Authority
  Butyrfentanyl is not recognized as safe or effective by the FDA, EMA, or any global veterinary or medical board. Its classification as a research chemical excludes it from therapeutic applications.

• High Risk of Respiratory Depression
  Like other fentanyl analogues, Butyrfentanyl carries a severe risk of respiratory depression, which can cause death within minutes if used improperly.

• Lack of Human Safety Data
  There are no clinical trials, dosage guidelines, or toxicity thresholds established for human use. All pharmacokinetic data is derived from in vitro or animal studies.

• Toxicology Reports Indicate Overdose Potential
  Forensic case studies have reported Butyrfentanyl in post-mortem toxicology screens, often in polydrug environments. These findings highlight its potential for accidental or intentional misuse.

• Legal Ramifications of Human Use
  Unauthorized administration or possession for human use is illegal in most countries and may result in criminal prosecution under controlled substances laws.
