Chemical Structure

Difenidol Impurity 10 CAS 5180-33-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Difenidol Impurity 10.

CATO supplies Difenidol Impurity 10 (CAS 5180-33-6), a pharmacopoeial impurity reference standard (molecular formula C15H16O, MW 212.29 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Difenidol Impurity 10 (C15H16O) contains a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 212.29 g/mol, it falls into the medium-molecular-weight range. 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 Difenidol Impurity 10 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.
