Chemical Structure

Metformin Impurity 22 CAS CATO-C4X-122022 chemical structure

Description

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Metformin Impurity 22 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Metformin Impurity 22 (CAS CATO-C4X-122022) is a certified pharmaceutical impurity reference standard with the molecular formula C4H10N4OHCl and a molecular weight of 166.61 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.
