Chemical Structure

Ramosetron impurity 32 CAS 167545-91-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 194.23 g/mol gives Ramosetron impurity 32 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ramosetron impurity 32 (CAS 167545-91-7), a pharmacopoeial impurity reference standard (molecular formula C10H14N2O2, MW 194.23 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Ramosetron impurity 32 (C10H14N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Ramosetron impurity 32 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.
