Chemical Structure

Nabumetone Impurity 12 CAS 2740579-68-2 chemical structure

Description

CATO supplies Nabumetone Impurity 12 (CAS 2740579-68-2), a pharmacopoeial impurity reference standard (molecular formula C15H14O3, MW 242.27 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Nabumetone Impurity 12 (C15H14O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 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 Nabumetone Impurity 12 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.
