u-47700 pink

Ultra-Potent “Pink” Opioid Standard for Receptor Research

U-47700—commonly nicknamed “Pink”—is a synthetic μ-opioid agonist prized in advanced studies of analgesic potency, receptor binding, and overdose toxicology. Delivering analgesic activity 7–10 × stronger than morphine in vitro, this compound gives scientists a precise benchmark for modeling novel opioid interactions, potency curves, and acute toxicity profiles under fully controlled laboratory conditions.

Laboratory-Verified Purity & Batch Consistency

Manufactured in GMP-aligned facilities and purified to ≥99 % GC/MS specifications, each batch of U-47700 is accompanied by a Certificate of Analysis (COA) detailing identity, purity, and residual-solvent screening. Tamper-evident, moisture-barrier packaging preserves chemical integrity from our lab to yours—supporting repeatable results in pharmacodynamic, SAR, and forensic investigations.

• Available as fine pink powder or compressed research pellets

• Stored in light-proof, nitrogen-flushed pouches for maximum stability

• Full traceability with lot numbers and analytical documentation

Essential Tool for Toxicology & SAR Modeling

Because of its high μ-receptor selectivity and well-characterized metabolic profile, U-47700 is routinely deployed in comparative potency studies, overdose response simulations, and analytical-method validations (LC–MS/MS, GC–MS). Its clear differentiation from fentanyl-class analogs makes it an invaluable control when mapping structure-activity relationships across emerging synthetic opioids.
