4h-Benzo[e][1,2,4]triazolo[5,1-c][1,2,4]thiadiazine-7-carboxylic acid 5,5-dioxide CAS 1311316-98-9 chemical structure

Description

The occurrence of 4h-Benzo[e][1,2,4]triazolo[5,1-c][1,2,4]thiadiazine-7-carboxylic acid 5,5-dioxide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4h-Benzo[e][1,2,4]triazolo[5,1-c][1,2,4]thiadiazine-7-carboxylic acid 5,5-dioxide (CAS 1311316-98-9) is a high-purity analytical reference standard with the molecular formula C9H6N4O4S and a molecular weight of 266.23 g/mol.

Structurally, 4h-Benzo[e][1,2,4]triazolo[5,1-c][1,2,4]thiadiazine-7-carboxylic acid 5,5-dioxide (C9H6N4O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 266.23 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).
