Chemical Structure

Aniline (Mesalazine EP Impurity K) CAS 62-53-3 chemical structure

Description

Aniline (Mesalazine EP Impurity K) (CAS 62-53-3) is a certified pharmaceutical impurity reference standard with the molecular formula C6H7N and a molecular weight of 93.13 g/mol.

The molecular framework of Aniline (Mesalazine EP Impurity K) (C6H7N) is characterized by a nitrile group, an aromatic ring system. 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 Aniline (Mesalazine EP Impurity K) 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.
