2,6-Dibromo-4-methylbenzene-1-sulfonyl chloride CAS 73732-31-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,6-Dibromo-4-methylbenzene-1-sulfonyl chloride.

2,6-Dibromo-4-methylbenzene-1-sulfonyl chloride (CAS 73732-31-7), molecular formula C7H5Br2ClO2S and molecular weight 348.44 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H5Br2ClO2S, 2,6-Dibromo-4-methylbenzene-1-sulfonyl chloride contains a sulfone 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 348.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
