Description
As a certified reference material (CRM), Betacarotene impurity 12 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Betacarotene impurity 12 (CAS CATO-C4X-281512) is a certified pharmaceutical impurity reference standard with the molecular formula C40H53O2 and a molecular weight of 565.85 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Betacarotene impurity 12 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 565.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
