Chemical Structure

4-Methyl-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine-7-sulfonyl chloride CAS 910037-13-7 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Methyl-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine-7-sulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.69 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).

4-Methyl-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine-7-sulfonyl chloride (CAS 910037-13-7), molecular formula C8H9ClN2O3S and molecular weight 248.69 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
