Chemical Structure

Vitamin K1 Impurity 31 CAS 19274-66-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 450.70 g/mol gives Vitamin K1 Impurity 31 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Vitamin K1 Impurity 31 (CAS 19274-66-9) is a certified pharmaceutical impurity reference standard with the molecular formula C31H46O2 and a molecular weight of 450.70 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Vitamin K1 Impurity 31 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 450.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 31 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.
