Chemical Structure

Menaquinone Impurity 45 CAS 112162-99-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Menaquinone Impurity 45.

CATO supplies Menaquinone Impurity 45 (CAS 112162-99-9), a pharmacopoeial impurity reference standard (molecular formula C19H30O3, MW 306.44 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, a hydroxyl group, an ether linkage, Menaquinone Impurity 45 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.44 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 Menaquinone Impurity 45 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.
