2,6-Dimethyl-3-oxo-3,4-dihydro-2H-1,4-benzoxazine-7-sulfonyl chloride CAS 1171749-11-3

Description

CATO manufactures 2,6-Dimethyl-3-oxo-3,4-dihydro-2H-1,4-benzoxazine-7-sulfonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies 2,6-Dimethyl-3-oxo-3,4-dihydro-2H-1,4-benzoxazine-7-sulfonyl chloride (CAS 1171749-11-3), a certified reference material (molecular formula C10H10ClNO4S, MW 275.71 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, chlorine substitution, 2,6-Dimethyl-3-oxo-3,4-dihydro-2H-1,4-benzoxazine-7-sulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 275.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
