Chemical Structure
Description
2-{[4-(4-chlorophenyl)-1,3-thiazol-2-yl]methyl}-2,3-dihydro-1h-isoindole-1,3-dione (C18H11ClN2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
2-{[4-(4-chlorophenyl)-1,3-thiazol-2-yl]methyl}-2,3-dihydro-1h-isoindole-1,3-dione (CAS 1193389-24-0), molecular formula C18H11ClN2O2S and molecular weight 354.81 g/mol, is a CATO reference standard with documented purity and traceability.
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.
