Dimenhydrinate EP Impurity I CAS 91-01-0 chemical structure

Description

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 supplies Dimenhydrinate EP Impurity I (CAS 91-01-0), a pharmacopoeial impurity reference standard (molecular formula C13H12O, MW 184.23 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C13H12O, Dimenhydrinate EP Impurity I contains a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 184.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Dimenhydrinate EP Impurity I 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.
