Description

(+/-)-3-Mercapto-1-Pentanol CAS NO 548740-99-4 is a chiral thiol-alcohol compound valued for its unique sulfur-containing functional group, which serves as a versatile building block in advanced organic synthesis. This compound is particularly significant for its role in creating complex molecules with specific stereochemistry and for introducing sulfur-based moieties that can impart distinct properties to the final product. It is primarily needed by research and development chemists in the pharmaceutical, agrochemical, and flavor & fragrance industries for applications ranging from asymmetric catalysis to the synthesis of bioactive intermediates.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring sulfur-containing stereocenters.
• Agrochemical Synthesis: Used in the research and development of novel pesticides and herbicides where the thiol group acts as a critical functional handle.
• Flavor & Fragrance Ingredient: Serves as a precursor for sulfur-containing flavor compounds that contribute to meaty, roasted, or tropical notes in food and perfumery.
• Ligand for Asymmetric Catalysis: Employed in the development of chiral ligands for metal-catalyzed reactions, enabling the production of enantiomerically pure compounds.
• Polymer Modification: Acts as a chain transfer agent or functional monomer to introduce thiol groups into polymers, altering their physical and chemical properties.
• Material Science Research: Utilized in surface functionalization and the creation of self-assembled monolayers (SAMs) on gold and other surfaces.
