Vitamin A impurity 27 CAS 62702-53-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Vitamin A impurity 27.

Vitamin A impurity 27 (CAS 62702-53-8) is a certified pharmaceutical impurity reference standard with the molecular formula C36H58O3 and a molecular weight of 538.84 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Vitamin A impurity 27 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 538.84 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 A impurity 27 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.
