1,3-Bis(4-chlorophenyl)thiourea (CAS 1220-00-4) is a high-purity analytical reference standard with the molecular formula C13H10Cl2N2S and a molecular weight of 297.20 g/mol.
1,3-Bis(4-chlorophenyl)thiourea (C13H10Cl2N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
