Chemical Structure

1-bromo-3-(chloromethyl)-5-nitro-benzene CAS 318261-49-3 chemical structure

Description

The occurrence of 1-bromo-3-(chloromethyl)-5-nitro-benzene is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-bromo-3-(chloromethyl)-5-nitro-benzene (CAS 318261-49-3) is a high-purity analytical reference standard with the molecular formula C7H11BrClNO2 and a molecular weight of 256.52 g/mol.

Structurally, 1-bromo-3-(chloromethyl)-5-nitro-benzene (C7H11BrClNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 256.52 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
