Chemical Structure

3-[(4-Methoxyphenyl)methyl]-3,4-dihydro-2H-1,3-benzothiazine-2,4-dione CAS 338401-62-0 chemical structure

Description

3-[(4-Methoxyphenyl)methyl]-3,4-dihydro-2H-1,3-benzothiazine-2,4-dione (CAS 338401-62-0), molecular formula C16H13NO3S and molecular weight 299.34 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H13NO3S, 3-[(4-Methoxyphenyl)methyl]-3,4-dihydro-2H-1,3-benzothiazine-2,4-dione contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 299.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 3-[(4-Methoxyphenyl)methyl]-3,4-dihydro-2H-1,3-benzothiazine-2,4-dione 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.
