Chemical Structure
Description
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.
(2Z)-2-(4-Chlorobenzenesulfonyl)-3-[4-(methylsulfanyl)phenyl]prop-2-enenitrile (CAS 556023-24-6), molecular formula C16H12ClNO2S2 and molecular weight 349.85 g/mol, is a CATO reference standard with documented purity and traceability.
(2Z)-2-(4-Chlorobenzenesulfonyl)-3-[4-(methylsulfanyl)phenyl]prop-2-enenitrile (C16H12ClNO2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
