Chemical Structure

N-Nitroso Melphalan EP Impurity K CAS 55-18-5 chemical structure

Description

As a process- or degradation-related impurity, N-Nitroso Melphalan EP Impurity K (CAS 55-18-5, C4H10N2O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

N-Nitroso Melphalan EP Impurity K (C4H10N2O) contains an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
