Chemical Structure

Methyl 2-{[1-({2-[(4-chlorophenyl)sulfanyl]ethyl}carbamoyl)ethyl]sulfanyl}benzoate CAS 337923-45-2 chemical structure

Description

Methyl 2-{[1-({2-[(4-chlorophenyl)sulfanyl]ethyl}carbamoyl)ethyl]sulfanyl}benzoate (CAS 337923-45-2), molecular formula C19H20ClNO3S2 and molecular weight 409.95 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 2-{[1-({2-[(4-chlorophenyl)sulfanyl]ethyl}carbamoyl)ethyl]sulfanyl}benzoate (C19H20ClNO3S2) contains a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
