4-Bromo-2-chloro-6-nitroaniline CAS 34033-41-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-2-chloro-6-nitroaniline.

CATO supplies 4-Bromo-2-chloro-6-nitroaniline (CAS 34033-41-5), a certified reference material (molecular formula C6H4BrClN2O2, MW 251.47 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H4BrClN2O2, 4-Bromo-2-chloro-6-nitroaniline contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 251.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
