Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 306.41 g/mol gives Tetrabenazine Impurity 31-D3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tetrabenazine Impurity 31-D3 (CAS CATO-C4X-274831), a pharmacopoeial impurity reference standard (molecular formula C18H22D3NO3, MW 306.41 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Tetrabenazine Impurity 31-D3 (C18H22D3NO3) contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 306.41 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), Tetrabenazine Impurity 31-D3 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.
