Chemical Structure

Lysine Impurity 17 CAS 923-27-3 chemical structure

Description

As a process- or degradation-related impurity, Lysine Impurity 17 (CAS 923-27-3, C6H14N2O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Lysine Impurity 17 (C6H14N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.

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.
