Chemical Structure
Description
1-(3-Methylbenzyl)-1H-benzo[c][1,2]thiazin-4(3H)-one 2,2-dioxide (CAS 1255783-92-6), molecular formula C16H15NO3S and molecular weight 301.36 g/mol, is a CATO reference standard with documented purity and traceability.
1-(3-Methylbenzyl)-1H-benzo[c][1,2]thiazin-4(3H)-one 2,2-dioxide (C16H15NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
