Description
As a certified reference material (CRM), 4-Phenyl-3,4-dihydro-2H-pyrido[2,3-e][1,2,4]thiadiazine 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.
CATO supplies 4-Phenyl-3,4-dihydro-2H-pyrido[2,3-e][1,2,4]thiadiazine 1,1-dioxide (CAS 1707737-24-3), a certified reference material (molecular formula C12H11N3O2S, MW 261.30 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-Phenyl-3,4-dihydro-2H-pyrido[2,3-e][1,2,4]thiadiazine 1,1-dioxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.30 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.
