4-Hydroxy-N-(2-methoxyphenyl)-1-methyl-2,2-dioxo-1,2-dihydro-2lambda~6~-thieno[3,2-c][1,2]thiazine-3-carbothioamide CAS 320423-79-8

Description

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

4-Hydroxy-N-(2-methoxyphenyl)-1-methyl-2,2-dioxo-1,2-dihydro-2lambda~6~-thieno[3,2-c][1,2]thiazine-3-carbothioamide (CAS 320423-79-8), molecular formula C15H14N2O4S3 and molecular weight 382.48 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Hydroxy-N-(2-methoxyphenyl)-1-methyl-2,2-dioxo-1,2-dihydro-2lambda~6~-thieno[3,2-c][1,2]thiazine-3-carbothioamide (C15H14N2O4S3) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
