Chemical Structure
Description
The occurrence of 6-Chloro-2-(5-(4-chlorophenyl)-1,3,4-oxadiazol-2-yl)-4-(methylsulfonyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-Chloro-2-(5-(4-chlorophenyl)-1,3,4-oxadiazol-2-yl)-4-(methylsulfonyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine (CAS 866135-01-5), a certified reference material (molecular formula C17H13Cl2N3O4S, MW 426.27 g/mol) for analytical method development and quality control.
Structurally, 6-Chloro-2-(5-(4-chlorophenyl)-1,3,4-oxadiazol-2-yl)-4-(methylsulfonyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine (C17H13Cl2N3O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 426.27 g/mol, it falls into the moderately-high-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), 6-Chloro-2-(5-(4-chlorophenyl)-1,3,4-oxadiazol-2-yl)-4-(methylsulfonyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
