Acetaminophen Impurity 19 CAS 98966-17-7

Description

Compared with other compounds in its class, the molecular weight of 300.31 g/mol gives Acetaminophen Impurity 19 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Acetaminophen Impurity 19 (CAS 98966-17-7) is a certified pharmaceutical impurity reference standard with the molecular formula C16H16N2O4 and a molecular weight of 300.31 g/mol.

The molecular framework of Acetaminophen Impurity 19 (C16H16N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Acetaminophen Impurity 19 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.
