Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,2-dimethyl-3,4-dihydro-2H-1,4-benzothiazine (CAS 93301-19-0), molecular formula C10H13NS and molecular weight 179.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,2-dimethyl-3,4-dihydro-2H-1,4-benzothiazine (C10H13NS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
