Chemical Structure

Lurasidone Impurity 56 CAS 173658-50-9 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.

Lurasidone Impurity 56 (CAS 173658-50-9) is a certified pharmaceutical impurity reference standard with the molecular formula C10H20O6S2 and a molecular weight of 300.39 g/mol.

Lurasidone Impurity 56 (C10H20O6S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
