3-{[(3-methylphenyl)methyl]sulfanyl}-4H-1lambda6,4-benzothiazine-1,1-dione CAS 477868-90-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-{[(3-methylphenyl)methyl]sulfanyl}-4H-1lambda6,4-benzothiazine-1,1-dione.

3-{[(3-methylphenyl)methyl]sulfanyl}-4H-1lambda6,4-benzothiazine-1,1-dione (CAS 477868-90-9), molecular formula C16H15NO2S2 and molecular weight 317.43 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-{[(3-methylphenyl)methyl]sulfanyl}-4H-1lambda6,4-benzothiazine-1,1-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 317.43 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).

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.
