Chemical Structure

Acetylcysteine Impurity N2 CAS 30452-69-8 chemical structure

Description

Acetylcysteine Impurity N2 (C6H12N2O6S2) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Acetylcysteine Impurity N2 (CAS 30452-69-8) is a certified pharmaceutical impurity reference standard with the molecular formula C6H12N2O6S2 and a molecular weight of 272.30 g/mol.

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.

As a certified reference material (CRM), Acetylcysteine Impurity N2 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
