Independent Third-Party Verification
Lab Results & Certificates of Analysis
Every batch of SR-17018 we ship is tested by an independent ISO/IEC 17025-accredited laboratory. This archive lists recent batch reports so researchers can verify purity, structural identity, and residual contaminants before purchase.
HPLC Purity
High-performance liquid chromatography confirms ≥99% active compound on every batch.
NMR Identity
Proton (¹H) and carbon (¹³C) NMR spectra confirm structural identity matches SR-17018.
Safety Panel
Residual-solvent screening (ICH Q3C) and heavy-metals testing (USP <232>) on every lot.
