Chemical Structure
Description
The occurrence of 4-(Bromomethyl)-2,1,3-benzothiadiazole is closely related to a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(Bromomethyl)-2,1,3-benzothiadiazole (CAS 16405-99-5), molecular formula C7H5BrN2S and molecular weight 229.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system, 4-(Bromomethyl)-2,1,3-benzothiadiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.10 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.
