Epinastine Impurity 54 CAS 25543-28-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 150.65 g/mol gives Epinastine Impurity 54 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Epinastine Impurity 54 (CAS 25543-28-6), a pharmacopoeial impurity reference standard (molecular formula C6H15ClN2, MW 150.65 g/mol) used for the identification and quantification of trace impurities in APIs.

Epinastine Impurity 54 (C6H15ClN2) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Epinastine Impurity 54 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.
