Chemical Structure

Tinidazole Impurity N1 CAS 52455-84-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tinidazole Impurity N1.

CATO supplies Tinidazole Impurity N1 (CAS 52455-84-2), a pharmacopoeial impurity reference standard (molecular formula C8H13N3O5S, MW 263.27 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Tinidazole Impurity N1 (C8H13N3O5S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.

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.
