Sarpogrelate Impurity 3 CAS 135963-42-7

Description

Compared with other compounds in its class, the molecular weight of 329.43 g/mol gives Sarpogrelate Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sarpogrelate Impurity 3 (CAS 135963-42-7) is a certified pharmaceutical impurity reference standard with the molecular formula C20H27NO3 and a molecular weight of 329.43 g/mol.

Based on its molecular formula C20H27NO3, Sarpogrelate Impurity 3 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 329.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
