Chemical Structure

Tedizolid Impurity 73 CAS 13566-35-3 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.

Tedizolid Impurity 73 (CAS 13566-35-3) is a certified pharmaceutical impurity reference standard with the molecular formula C6H6N6 and a molecular weight of 162.15 g/mol.

The molecular framework of Tedizolid Impurity 73 (C6H6N6) is characterized by a nitrile group, an aromatic ring system. 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).

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.
