Compared with other compounds in its class, the molecular weight of 388.76 g/mol gives 7-Chloro-4-{[(2,6-dichlorophenyl)methyl]sulfanyl}-2,3-dihydro-1,5-benzothiazepine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-Chloro-4-{[(2,6-dichlorophenyl)methyl]sulfanyl}-2,3-dihydro-1,5-benzothiazepine (CAS 320423-90-3), molecular formula C16H12Cl3NS2 and molecular weight 388.76 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Chloro-4-{[(2,6-dichlorophenyl)methyl]sulfanyl}-2,3-dihydro-1,5-benzothiazepine (C16H12Cl3NS2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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 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.
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.
