Description
Ornidazole Impurity 80 (CAS CATO-C4X-133180) is a certified pharmaceutical impurity reference standard with the molecular formula C7H10ClN4O8P and a molecular weight of 344.60 g/mol.
Ornidazole Impurity 80 (C7H10ClN4O8P) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
