5-(4-Tert-butylphenyl)-4-(4-ethoxyphenyl)-4h-1,2,4-triazole-3-thiol (CAS 731802-52-1) is a high-purity analytical reference standard with the molecular formula C20H23N3OS and a molecular weight of 353.48 g/mol.
5-(4-Tert-butylphenyl)-4-(4-ethoxyphenyl)-4h-1,2,4-triazole-3-thiol (C20H23N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.
