About the compound
What is SR-17018?
SR-17018 is a preclinical μ-opioid receptor research compound studied for biased signaling, intrinsic efficacy, tolerance, and analgesic side-effect separation. It is supplied as precision powder for research use only and is not approved for human use.
Each released batch is independently verified for identity and purity, and the current batch COA is published publicly so research customers can audit what they ordered before it ships.

Frequently asked
Everything you need to know.
SR-17018 is a preclinical μ-opioid receptor research tool used in studies of biased signaling, intrinsic efficacy, tolerance, and analgesic side-effect separation. It has not been approved for human use or evaluated in human clinical trials. For the full pharmacology, see the mechanism of action page.
Every batch is third-party verified by HPLC for purity and by mass spectrometry and ¹H NMR for identity. Purity must meet a ≥ 99% threshold — above the ≥ 98% minimum common in the research-reagent market — before a certificate of analysis is issued and the batch is released. The current batch COA is published on the Batch Results & COAs page.
No. SR-17018 is not approved for human use and has not entered human clinical trials. It remains a preclinical research compound.
SR-17018 is currently supplied as precision powder for qualified researchers who want flexible handling, clear documentation, and consistent batch transparency. See how SR-17018 is supplied for details.
Store sealed, dry, and protected from light. Recommended storage is standard refrigeration at 36–46°F. If solutions are prepared, aliquot and refrigerate or freeze appropriately to minimize repeated handling. Full storage, solvent-compatibility, PPE, and stock-solution guidance is on the safety and handling page.
