Chemical Structure

Erlotinib Impurity 115 CAS 52670-38-9 chemical structure

Description

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.

CATO supplies Erlotinib Impurity 115 (CAS 52670-38-9), a pharmacopoeial impurity reference standard (molecular formula C8H7N, MW 117.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Erlotinib Impurity 115 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 117.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
