Description

Cyclohexanethiol, 1-Ethynyl- (6Ci) CAS NO 98559-20-7 is a specialized organosulfur compound featuring a reactive thiol group and an ethynyl moiety on a cyclohexane ring. This unique bifunctional structure makes it a valuable building block for synthesizing complex molecules in advanced research and fine chemical manufacturing. It is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science sectors for applications requiring precise molecular modifications.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, particularly those targeting neurological or metabolic pathways.
• Agrochemical Synthesis: Used in the development of new pesticides and herbicides, where the thiol and alkyne groups enable the creation of specific bioactive structures.
• Ligand and Catalyst Development: Employed in the preparation of specialized ligands for transition metal catalysis, enhancing reaction selectivity and efficiency.
• Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce sulfur-containing or alkyne-functionalized side chains into polymers for advanced material properties.
• Chemical Biology Probes: Utilized in "click chemistry" applications to create bioconjugates or labeling probes due to the reactivity of the ethynyl group.
• Flavor & Fragrance Chemistry: Potential intermediate for synthesizing complex sulfur-containing aroma compounds.
