Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 206.16 g/mol gives Pretomanid Impurity 30 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Pretomanid Impurity 30 (CAS 2923894-84-0), a pharmacopoeial impurity reference standard (molecular formula C9H9F3O2, MW 206.16 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Pretomanid Impurity 30 (C9H9F3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 206.16 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Pretomanid Impurity 30 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.
