Dimethyl sebacate

Dimethyl Sebacate (DMS) is an important organic compound with primary applications spanning the following fields:

I. Polymer Material Processing

1. Plasticizer and Softener

   • Acts as a plasticizer for cellulose resins (such as ethyl cellulose), vinyl resins (e.g., PVC), and synthetic rubbers (e.g., rubber, chloroprene rubber), significantly enhancing material flexibility, low-temperature brittleness resistance, and processing fluidity, particularly suitable for cold-resistant products.
   • Exhibits good compatibility with resins like polymethyl methacrylate and polystyrene, and can serve as an alternative to traditional phthalate plasticizers.

2. Solvent

   • Dissolves polymers such as chlorinated rubber and polyvinyl butyral, used for optimizing formulations in coatings and adhesives.

II. Raw Material for Light Stabilizer Synthesis

• Core Intermediate: Used in the production of hindered amine light stabilizer (HALS) series products (e.g., UV-770, UV-750, UV-123), enhancing the light aging resistance of plastics and coatings.

III. Organic Synthesis and Pharmaceutical Fields

1. Intermediate Applications

   • Participates in reactions such as ester exchange and hydrolysis to derivatively prepare pharmaceutical intermediates, fragrances, and specialty chemicals.
   • Used in synthesizing cold-resistant plasticizers (e.g., dibutyl sebacate, dioctyl sebacate) and raw materials for lubricating grease.

2. Pharmaceutical Carrier and Controlled Release Systems

   • Leveraging its biocompatibility, it serves as a component in drug carriers for targeted drug delivery technologies.

IV. Lubricants and Specialized Industries

1. Lubricant Raw Material
   • Functions as a foundational component in synthesizing high-temperature resistant lubricants, improving the low-temperature performance of greases (maintaining fluidity at -55°C).
2. New Energy Materials
   • Used as an additive in electrolyte solutions for energy storage flow batteries to optimize electrochemical performance.

V. Other High-End Applications

• Aerospace: Component of cold-resistant lubricating grease, ensuring equipment operation in extreme low-temperature environments.
• Cosmetics and Fragrances: Used in formulating fruity and floral fragrances, and as an emulsifier in skincare products.
• Eco-Friendly Coatings: Serves as a modifier for alkyd resins, enhancing coating weather resistance.

Key Physical Properties and Safety

Operational Warning: Harmful if swallowed, irritating to skin/eyes; protective equipment required; leakage into water bodies poses hazards to aquatic organisms.
