Chemical Structure

N-Nitroso Chlorcyclizine EP Impurity A CAS 16339-07-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Nitroso Chlorcyclizine EP Impurity A.

CATO supplies N-Nitroso Chlorcyclizine EP Impurity A (CAS 16339-07-4), a pharmacopoeial impurity reference standard (molecular formula C5H11N3O, MW 129.16 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C5H11N3O, N-Nitroso Chlorcyclizine EP Impurity A contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 129.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
