Chemical Structure

Salbutamol Impurity 134 CAS 115787-50-3 chemical structure

Description

CATO manufactures Salbutamol Impurity 134 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.

As a process- or degradation-related impurity, Salbutamol Impurity 134 (CAS 115787-50-3, C9H7BrO3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Salbutamol Impurity 134 (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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
