Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 437.37 g/mol gives Sarpogrelate impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sarpogrelate impurity 15 (CAS CATO-C4X-291315) is a certified pharmaceutical impurity reference standard with the molecular formula C16H21NO6C2HF3O2 and a molecular weight of 437.37 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Sarpogrelate impurity 15 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 437.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
