3,4-Dihydro-2H-pyrazolo[1,5-e][1,2,5]thiadiazine-8-carboxylic acid 1,1-dioxide CAS 2138111-19-8

Description

3,4-Dihydro-2H-pyrazolo[1,5-e][1,2,5]thiadiazine-8-carboxylic acid 1,1-dioxide (C6H7N3O4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
