Chemical Structure
Description
5-(2-Chlorophenyl)-7-ethyl-1,3-dihydro-2H-thieno[2,3-e][1,4]diazepine-2-thione (C15H13ClN2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
5-(2-Chlorophenyl)-7-ethyl-1,3-dihydro-2H-thieno[2,3-e][1,4]diazepine-2-thione (CAS 40054-40-8) is a high-purity analytical reference standard with the molecular formula C15H13ClN2S2 and a molecular weight of 320.86 g/mol.
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.
