Chemical Structure

Indacaterol Impurity 42 CAS CATO-C4X-150042 chemical structure

Description

The occurrence of Indacaterol Impurity 42 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Indacaterol Impurity 42 (CAS CATO-C4X-150042), a pharmacopoeial impurity reference standard (molecular formula C18H15Br2NO3, MW 453.12 g/mol) used for the identification and quantification of trace impurities in APIs.

Indacaterol Impurity 42 (C18H15Br2NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Indacaterol Impurity 42 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.
