Description

Cyclohexyl 3-Mercaptopropionate is a specialized organosulfur compound featuring a thiol (mercapto) functional group. This chemical is valued for its role as a versatile intermediate and chain transfer agent in polymer synthesis and organic transformations. It is primarily sought by manufacturers in the polymer, specialty chemical, and pharmaceutical industries for applications requiring precise molecular weight control or the introduction of sulfur-based functionalities.

Application

• Polymer Industry: Acts as an effective chain transfer agent (CTA) in free-radical polymerization processes, such as for acrylics and styrenics, to regulate polymer molecular weight and polydispersity.
• Organic Synthesis: Serves as a key intermediate for introducing the cyclohexyl 3-mercaptopropionate moiety into more complex molecules in pharmaceutical and agrochemical research.
• Crosslinking Agent: Utilized in the formulation of specialty resins and coatings where the thiol group participates in thiol-ene click chemistry or other crosslinking reactions.
• Lubricant & Fuel Additive Precursor: Used in the synthesis of sulfur-containing additives that can improve the extreme pressure (EP) properties of lubricants or act as stabilizers.
• Adhesive Formulations: Incorporated as a modifying agent in certain adhesive systems to enhance flexibility, adhesion, or curing characteristics.

Quality Control

Our Cyclohexyl 3-Mercaptopropionate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay (by GC or HPLC), identity confirmation (IR), and impurity profiling, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) documenting purity, physical properties, and test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to keep the container under a nitrogen atmosphere after opening and to minimize exposure to air and heat sources.
