Chemical Structure
Description
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO supplies Ornidazole Impurity 79 (CAS CATO-C4X-133179), a pharmacopoeial impurity reference standard (molecular formula C6H9ClN3O6P, MW 285.58 g/mol) used for the identification and quantification of trace impurities in APIs.
Ornidazole Impurity 79 (C6H9ClN3O6P) contains a carbohydrate-derived structure, an amide group, a phosphate ester group, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Ornidazole Impurity 79 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.
