Chemical Structure

Salbutamol EP Impurity B CAS 96948-64-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 209.28 g/mol gives Salbutamol EP Impurity B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Salbutamol EP Impurity B (CAS 96948-64-0), a pharmacopoeial impurity reference standard (molecular formula C12H19NO2, MW 209.28 g/mol) used for the identification and quantification of trace impurities in APIs.

Salbutamol EP Impurity B (C12H19NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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).

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 EP Impurity B 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.
