5-((3-(4-Chlorophenyl)-1-phenyl-1H-pyrazol-4-yl)methylene)-3-methyl-2-thioxothiazolidin-4-one CAS 623936-02-7

Description

5-((3-(4-Chlorophenyl)-1-phenyl-1H-pyrazol-4-yl)methylene)-3-methyl-2-thioxothiazolidin-4-one (C20H14ClN3OS2) contains a steroid core, an amide group, sulfur-containing functionality, 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; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

5-((3-(4-Chlorophenyl)-1-phenyl-1H-pyrazol-4-yl)methylene)-3-methyl-2-thioxothiazolidin-4-one (CAS 623936-02-7) is a high-purity analytical reference standard with the molecular formula C20H14ClN3OS2 and a molecular weight of 411.93 g/mol.
