4-(Ethylsulfanyl)-11,13-dimethyl-6-(phenylsulfanyl)-8-thia-3,5,10-triazatricyclo[7.4.0.0^{2,7}]trideca-1(13),2(7),3,5,9,11-hexaene (CAS 478065-74-6) is a high-purity analytical reference standard with the molecular formula C19H17N3S3 and a molecular weight of 383.55 g/mol.
4-(Ethylsulfanyl)-11,13-dimethyl-6-(phenylsulfanyl)-8-thia-3,5,10-triazatricyclo[7.4.0.0^{2,7}]trideca-1(13),2(7),3,5,9,11-hexaene (C19H17N3S3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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.
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.
