Chemical Structure

2-Dimethylsulfonamidophenothiazine CAS 1090-78-4 chemical structure

Description

2-Dimethylsulfonamidophenothiazine (CAS 1090-78-4), molecular formula C14H14N2O2S2 and molecular weight 306.40 g/mol, is a CATO reference standard with documented purity and traceability.

2-Dimethylsulfonamidophenothiazine (C14H14N2O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 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.
