Chemical Structure

Tropisetron EP Impurity A CAS 120-29-6 chemical structure

Description

CATO supplies Tropisetron EP Impurity A (CAS 120-29-6), a pharmacopoeial impurity reference standard (molecular formula C8H15NO, MW 141.21 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Tropisetron EP Impurity A (C8H15NO) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Tropisetron EP Impurity A 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.
