Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Tetrabenazine Impurity 48 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.40 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.
CATO supplies Tetrabenazine Impurity 48 (CAS 1214267-46-5), a pharmacopoeial impurity reference standard (molecular formula C18H25NO3, MW 303.40 g/mol) used for the identification and quantification of trace impurities in APIs.
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.
As a certified reference material (CRM), Tetrabenazine Impurity 48 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.
