Chemical Structure

Linagliptin Impurity N14 CAS 127294-73-9 chemical structure

Description

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.

CATO supplies Linagliptin Impurity N14 (CAS 127294-73-9), a pharmacopoeial impurity reference standard (molecular formula C5H12N2, MW 100.17 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C5H12N2, Linagliptin Impurity N14 contains an organic framework; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 100.17 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.
