1-{2-[(4-chlorophenyl)sulfanyl]phenyl}-2,5-dihydro-1H-pyrrole-2,5-dione CAS 568550-95-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-{2-[(4-chlorophenyl)sulfanyl]phenyl}-2,5-dihydro-1H-pyrrole-2,5-dione.

1-{2-[(4-chlorophenyl)sulfanyl]phenyl}-2,5-dihydro-1H-pyrrole-2,5-dione (CAS 568550-95-8), molecular formula C16H10ClNO2S and molecular weight 315.77 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H10ClNO2S, 1-{2-[(4-chlorophenyl)sulfanyl]phenyl}-2,5-dihydro-1H-pyrrole-2,5-dione contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 315.77 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
