Drotaverin Impurity 73 CAS CATO-C4X-243573

Description

Compared with other compounds in its class, the molecular weight of 194.27 g/mol gives Drotaverin Impurity 73 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Drotaverin Impurity 73 (CAS CATO-C4X-243573) is a certified pharmaceutical impurity reference standard with the molecular formula C12H18O2 and a molecular weight of 194.27 g/mol.

Based on its molecular formula C12H18O2, Drotaverin Impurity 73 contains a carboxylic acid group, 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 194.27 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).

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 Drotaverin Impurity 73 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.
