Description
5-(4-Chlorophenyl)-4H-1,2,4-triazole-3-thiol is an aromatic heterocyclic thiol used as a versatile building block in organic and medicinal chemistry. It carries CAS number 26028-65-9 and the empirical formula C₈H₆ClN₃S, with a molar mass of 211,67 g/mol. The 1,2,4-triazole scaffold bearing a 4-chlorophenyl substituent and a free thiol offers handles for alkylation, metal coordination, and further ring functionalisation in hit-to-lead and intermediate synthesis. Its well-defined molecular mass facilitates precise weighing and stoichiometric planning in multi-step sequences. Researchers working on bioactive heterocycles, agrochemical leads, or sulphur-containing ligands can incorporate this reagent into conjugation, cyclisation, and library-expansion workflows. Suitable for controlled laboratory applications in biochemical and fine-chemical research environments requiring a chlorophenyl-triazole-thiol intermediate.

Questions about 5-(4-Chlorophenyl)-4H-1,2,4-triazole-3-t, hiol, 250 mg
What is this article?
5-(4-Chlorophenyl)-4H-1,2,4-triazole-3-t, hiol, 250 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
