Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-N-(2-((4-fluorobenzyl)thio)-2-methylpropyl)benzenesulfonamide.
4-Chloro-N-(2-((4-fluorobenzyl)thio)-2-methylpropyl)benzenesulfonamide (CAS 339104-53-9), molecular formula C17H19ClFNO2S2 and molecular weight 387.92 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-N-(2-((4-fluorobenzyl)thio)-2-methylpropyl)benzenesulfonamide (C17H19ClFNO2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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.
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.
