(E)-5-(2-Hydroxybenzylidene)-2-thioxoimidazolidin-4-one CAS 139554-57-7

Description

The occurrence of (E)-5-(2-Hydroxybenzylidene)-2-thioxoimidazolidin-4-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(E)-5-(2-Hydroxybenzylidene)-2-thioxoimidazolidin-4-one (CAS 139554-57-7) is a high-purity analytical reference standard with the molecular formula C10H8N2O2S and a molecular weight of 220.25 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (E)-5-(2-Hydroxybenzylidene)-2-thioxoimidazolidin-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
