Chemical Structure

3-(Bromomethyl)-1,2-dichloro-4-nitrobenzene CAS 93213-79-7 chemical structure

Description

3-(Bromomethyl)-1,2-dichloro-4-nitrobenzene (C7H4BrCl2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

3-(Bromomethyl)-1,2-dichloro-4-nitrobenzene (CAS 93213-79-7), molecular formula C7H4BrCl2NO2 and molecular weight 284.92 g/mol, is a CATO reference standard with documented purity and traceability.

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.
