Chemical Structure

Famotidine Impurity 43 CAS 29671-92-9 chemical structure

Description

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO supplies Famotidine Impurity 43 (CAS 29671-92-9), a pharmacopoeial impurity reference standard (molecular formula CH3ClN2HCl, MW 114.96 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to chlorine substitution, Famotidine Impurity 43 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 114.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO manufactures Famotidine Impurity 43 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.
