Chemical Structure

Picosulfate impurity 24 CAS CATO-C4X-123724 chemical structure

Description

Picosulfate impurity 24 (CAS CATO-C4X-123724) is a certified pharmaceutical impurity reference standard with the molecular formula C18H13NO8S2Na and a molecular weight of 458.41 g/mol.

Based on its molecular formula C18H13NO8S2Na, Picosulfate impurity 24 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 458.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
