Chemical Structure
Description
The occurrence of (5Z)-5-[(5-Chloro-1,3-dimethyl-1H-pyrazol-4-yl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(5Z)-5-[(5-Chloro-1,3-dimethyl-1H-pyrazol-4-yl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one (CAS 956206-97-6) is a high-purity analytical reference standard with the molecular formula C9H8ClN3OS2 and a molecular weight of 273.76 g/mol.
The molecular framework of (5Z)-5-[(5-Chloro-1,3-dimethyl-1H-pyrazol-4-yl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one (C9H8ClN3OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
