5-Bromo-6,7-difluoro-1,2-dimethyl-1,3-benzodiazole CAS 1393442-43-7

Description

Compared with other compounds in its class, the molecular weight of 261.07 g/mol gives 5-Bromo-6,7-difluoro-1,2-dimethyl-1,3-benzodiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Bromo-6,7-difluoro-1,2-dimethyl-1,3-benzodiazole (CAS 1393442-43-7), molecular formula C9H7BrF2N2 and molecular weight 261.07 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Bromo-6,7-difluoro-1,2-dimethyl-1,3-benzodiazole (C9H7BrF2N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
