Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Methyl-2-oxo-3,4-dihydro-2H-benzo-[e][1,3]oxazine-6-sulfonyl chloride.
CATO supplies 3-Methyl-2-oxo-3,4-dihydro-2H-benzo-[e][1,3]oxazine-6-sulfonyl chloride (CAS 1383579-87-0), a certified reference material (molecular formula C9H8ClNO4S, MW 261.68 g/mol) for analytical method development and quality control.
Structurally, 3-Methyl-2-oxo-3,4-dihydro-2H-benzo-[e][1,3]oxazine-6-sulfonyl chloride (C9H8ClNO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 261.68 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3-Methyl-2-oxo-3,4-dihydro-2H-benzo-[e][1,3]oxazine-6-sulfonyl chloride 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.
