3-Bromo-2-methylbenzene-1-sulfonyl Chloride CAS 886501-61-7

Description

Compared with other compounds in its class, the molecular weight of 269.54 g/mol gives 3-Bromo-2-methylbenzene-1-sulfonyl Chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Bromo-2-methylbenzene-1-sulfonyl Chloride (CAS 886501-61-7), molecular formula C7H6BrClO2S and molecular weight 269.54 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, 3-Bromo-2-methylbenzene-1-sulfonyl Chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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

As a certified reference material (CRM), 3-Bromo-2-methylbenzene-1-sulfonyl Chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
