Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Oxo-3,4-dihydro-2h-benzo[e][1,2,3]thiadiazine-7-carbohydrazide 1,1-dioxide.
CATO supplies 4-Oxo-3,4-dihydro-2h-benzo[e][1,2,3]thiadiazine-7-carbohydrazide 1,1-dioxide (CAS 731826-77-0), a certified reference material (molecular formula C8H8N4O4S, MW 256.24 g/mol) for analytical method development and quality control.
Structurally, 4-Oxo-3,4-dihydro-2h-benzo[e][1,2,3]thiadiazine-7-carbohydrazide 1,1-dioxide (C8H8N4O4S) 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 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 256.24 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.
As a certified reference material (CRM), 4-Oxo-3,4-dihydro-2h-benzo[e][1,2,3]thiadiazine-7-carbohydrazide 1,1-dioxide 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.
