Chemical Structure

Salbutamol Impurity 146 CAS 124658-76-0 chemical structure

Description

The occurrence of Salbutamol Impurity 146 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Salbutamol Impurity 146 (CAS 124658-76-0), a pharmacopoeial impurity reference standard (molecular formula C9H7BrO3, MW 243.05 g/mol) used for the identification and quantification of trace impurities in APIs.

Salbutamol Impurity 146 (C9H7BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 146 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.
