Chemical Structure

Salbutamol Impurity 179 CAS CATO-C4X-1176179 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Salbutamol Impurity 179.

CATO supplies Salbutamol Impurity 179 (CAS CATO-C4X-1176179), a pharmacopoeial impurity reference standard (molecular formula C20H26N2O6S, MW 422.50 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C20H26N2O6S, Salbutamol Impurity 179 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 422.50 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.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Salbutamol Impurity 179 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.
