2,4-Dichloro-3-methylbenzene-1-sulfonyl chloride CAS 69145-58-0

Description

The occurrence of 2,4-Dichloro-3-methylbenzene-1-sulfonyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,4-Dichloro-3-methylbenzene-1-sulfonyl chloride (CAS 69145-58-0) is a high-purity analytical reference standard with the molecular formula C7H5Cl3O2S and a molecular weight of 259.54 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,4-Dichloro-3-methylbenzene-1-sulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 259.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
