Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Vitamin K1 Impurity 38 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 448.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Vitamin K1 Impurity 38 (CAS CATO-C4X-220738) is a certified pharmaceutical impurity reference standard with the molecular formula C31H44O2 and a molecular weight of 448.68 g/mol.
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 Vitamin K1 Impurity 38 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.
