Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 240.06 g/mol gives Tedizolid Impurity 75 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Tedizolid Impurity 75 (CAS CATO-C4X-105475, C7H6BrN5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Tedizolid Impurity 75 (C7H6BrN5) contains a nitrile group, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
