Chemical Structure
Description
As a certified reference material (CRM), Pilocarpine Impurity 8 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.
CATO supplies Pilocarpine Impurity 8 (CAS CATO-C4X-24018), a pharmacopoeial impurity reference standard (molecular formula C7H8O4, MW 156.14 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C7H8O4, Pilocarpine Impurity 8 contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 156.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
