Chemical Structure

Niraparib Impurity N2 CAS 1334823-70-9 chemical structure

Description

Based on its molecular formula C11H16N2, Niraparib Impurity N2 contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 176.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO supplies Niraparib Impurity N2 (CAS 1334823-70-9), a pharmacopoeial impurity reference standard (molecular formula C11H16N2, MW 176.26 g/mol) used for the identification and quantification of trace impurities in APIs.

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.
