Description

Compared with other compounds in its class, the molecular weight of 331.82 g/mol gives 1-(4-Chlorophenyl)-3-[(4-methylphenyl)sulfanyl]pyrrolidine-2,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(4-Chlorophenyl)-3-[(4-methylphenyl)sulfanyl]pyrrolidine-2,5-dione (CAS 321433-56-1), a certified reference material (molecular formula C17H14ClNO2S, MW 331.82 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(4-Chlorophenyl)-3-[(4-methylphenyl)sulfanyl]pyrrolidine-2,5-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 331.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 1-(4-Chlorophenyl)-3-[(4-methylphenyl)sulfanyl]pyrrolidine-2,5-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
