Description
CATO manufactures Naltrexone Hydrochloride Dihydrate - API Standards under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Naltrexone Hydrochloride Dihydrate - API Standards (CAS 850808-02-5), molecular formula C20H23NO4HClH2O and molecular weight 395.88 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Naltrexone Hydrochloride Dihydrate - API Standards (C20H23NO4HClH2O) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
