Chemical Structure

Bisnorlipoic Impurity N1 CAS 13125-44-5 chemical structure

Description

Bisnorlipoic Impurity N1 (C6H10O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

Bisnorlipoic Impurity N1 (CAS 13125-44-5) is a certified pharmaceutical impurity reference standard with the molecular formula C6H10O2S2 and a molecular weight of 178.27 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.

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.
