Description

2,6-Dichlorobenzenethiol (CAS No. 24966-39-0) is a high-purity aromatic thiol compound with the molecular formula C6H4Cl2S. This specialized chemical features two chlorine substituents at the 2 and 6 positions of the benzene ring, making it a valuable intermediate in organic synthesis and material science applications. Available in >98% purity by GC analysis, this crystalline solid (melting point 32-36°C) is packaged under inert atmosphere to prevent oxidation. The product is particularly useful as a building block for pharmaceutical active ingredients, ligands for transition metal catalysts, and as a precursor for functionalized polymers. Care should be taken when handling due to its thiol functionality – store at 2-8°C in tightly sealed containers away from oxidizers.
