Paracetamol EP Impurity N CAS 3070-86-8 chemical structure

Description

CATO supplies Paracetamol EP Impurity N (CAS 3070-86-8), a pharmacopoeial impurity reference standard (molecular formula C16H16N2O3, MW 284.31 g/mol) used for the identification and quantification of trace impurities in APIs.

Paracetamol EP Impurity N (C16H16N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.

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 manufactures Paracetamol EP Impurity N under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
