Chemical Structure
Description
The occurrence of Diosmin EP Impurity C-d4 (Isorhoifolin-d4) is closely related to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diosmin EP Impurity C-d4 (Isorhoifolin-d4) (CAS CATO-C4X-115613) is a certified pharmaceutical impurity reference standard with the molecular formula C27H26D4O14 and a molecular weight of 582.54 g/mol.
Based on its molecular formula C27H26D4O14, Diosmin EP Impurity C-d4 (Isorhoifolin-d4) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 582.54 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 Diosmin EP Impurity C-d4 (Isorhoifolin-d4) 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.
