3-Bromo-5-iodo-4-methylbenzoic acid CAS 1229245-20-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Bromo-5-iodo-4-methylbenzoic acid.

3-Bromo-5-iodo-4-methylbenzoic acid (CAS 1229245-20-8) is a high-purity analytical reference standard with the molecular formula C8H6BrIO2 and a molecular weight of 340.94 g/mol.

Based on its molecular formula C8H6BrIO2, 3-Bromo-5-iodo-4-methylbenzoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 340.94 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
