Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
(S)-1-(4-(Difluoromethoxy)phenyl)ethan-1-amine hydrochloride (CAS 2045362-22-7), molecular formula C9H11F2NOHCl and molecular weight 223.65 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-1-(4-(Difluoromethoxy)phenyl)ethan-1-amine hydrochloride (C9H11F2NOHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
