4-[4-(4-Chlorophenyl)-1,3-thiazol-2-yl]-1H-pyrazol-5-amine (CAS 667399-98-6) is a high-purity analytical reference standard with the molecular formula C12H9ClN4S and a molecular weight of 276.74 g/mol.
4-[4-(4-Chlorophenyl)-1,3-thiazol-2-yl]-1H-pyrazol-5-amine (C12H9ClN4S) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
