U-47700

Overview of U-47700

U-47700 — sometimes referred to in scientific literature as “Pink” or “U4” — is a synthetic opioid research compound first synthesized by scientists at The Upjohn Company during the 1970s as part of a broader investigation into non-morphine analgesic scaffolds. As a member of the Legacy Synthetic Opioid class, U-47700 exhibits high-affinity binding to the mu-opioid receptor (MOR), making it an invaluable tool compound for researchers investigating opioid receptor pharmacology, pain pathway signaling, and the structure-activity relationships (SAR) of benzamide-class opioids.

Chemically characterized as 3,4-Dichloro-N-[2-(dimethylamino)cyclohexyl]-N-methylbenzamide, U-47700 possesses a molecular formula of C₁₄H₂₀Cl₂N₂O and a molecular weight of approximately 329.2 g/mol. Its distinct dichlorobenzamide scaffold differentiates it structurally from classical opioids such as morphine or fentanyl, offering researchers a unique chemical probe for comparative receptor binding studies. When you buy U-47700 from Cayman Chemical Company, you receive a certified reference standard supported by full analytical documentation including NMR, HPLC purity data, and a Certificate of Analysis (CoA).

This compound is intended strictly for in vitro research, forensic reference, and analytical laboratory use only. It is not for human or veterinary consumption. Researchers working in toxicology, forensic chemistry, and pharmacology will find U-47700 for sale here as an authenticated standard that meets rigorous quality benchmarks essential for reproducible scientific results.

Frequently Asked Questions

What is U-47700 used for in scientific research?

U-47700 is primarily used as a mu-opioid receptor (MOR) agonist reference standard in pharmacological and forensic research settings. Scientists employ it in radioligand binding assays, functional receptor activity studies, and structure-activity relationship (SAR) investigations of benzamide-class opioids. It also serves as an authenticated reference material in forensic toxicology laboratories for identifying and quantifying the compound in biological specimens such as blood, urine, and tissue samples. Its unique dichlorobenzamide scaffold makes it particularly valuable for comparative studies against classical opioids.

How does U-47700 compare to other legacy synthetic opioids like MPPP?

While both U-47700 and MPPP (2g) are classified as legacy synthetic opioid research compounds, they differ significantly in their chemical scaffolds and receptor interaction profiles. U-47700 is a benzamide-class MOR agonist, whereas MPPP belongs to the 4-phenylpiperidine class and is structurally related to meperidine. This makes them complementary reference tools: researchers studying opioid receptor diversity, selectivity profiling, or multi-compound forensic panels will benefit from having both compounds available. Together they support a broader understanding of synthetic opioid pharmacology across different structural classes found in the Legacy Synthetic Opioid category.
