Sodium Picosulfate Impurity 11 CAS 1121-60-4 chemical structure

Description

CATO manufactures Sodium Picosulfate Impurity 11 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Sodium Picosulfate Impurity 11 (CAS 1121-60-4) is a certified pharmaceutical impurity reference standard with the molecular formula C6H5NO and a molecular weight of 107.11 g/mol.

Based on its molecular formula C6H5NO, Sodium Picosulfate Impurity 11 contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 107.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
