Amifostine Impurity 3 CAS CATO-C4X-19053

Description

Compared with other compounds in its class, the molecular weight of 228.25 g/mol gives Amifostine Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Amifostine Impurity 3 (CAS CATO-C4X-19053), a pharmacopoeial impurity reference standard (molecular formula C6H17N2O3PS, MW 228.25 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C6H17N2O3PS, Amifostine Impurity 3 contains an amide group, a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 228.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 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 manufactures Amifostine Impurity 3 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.
