Chemical Structure
Description
4-Methoxy-2,1,3-benzothiadiazole (CAS 1753-23-7), molecular formula C7H6N2OS and molecular weight 166.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Methoxy-2,1,3-benzothiadiazole (C7H6N2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 166.20 g/mol, it falls into the medium-molecular-weight range. 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.
