In the vast landscape of chemical manufacturing, certain intermediates play a pivotal role across multiple industries. Stearoyl Chloride (CAS 112-76-5) is one such compound, valued for its reactivity and versatility as an acylating agent. Whether you're involved in producing advanced pharmaceuticals, high-performance surfactants, or specialized industrial materials, understanding the utility of this yellow transparent oily liquid is essential. For companies looking to buy Stearoyl Chloride, identifying its broad industrial relevance is the first step.

Understanding Stearoyl Chloride's Chemical Foundation

Stearoyl Chloride is derived from stearic acid and is classified as an acyl chloride. Its chemical formula, C18H35ClO, indicates a long aliphatic chain (18 carbons) attached to a reactive carbonyl chloride group. This structure makes it highly susceptible to nucleophilic attack, leading to the formation of esters, amides, and anhydrides. Its common assay is 98% minimum, ensuring sufficient purity for most industrial applications. While sensitive to moisture, it is a stable compound when stored correctly. As a trusted manufacturer and supplier, we ensure consistent quality for all your needs.

Key Industrial Applications of Stearoyl Chloride

The inherent reactivity and structural characteristics of Stearoyl Chloride enable its use in a diverse range of sectors:

  • Pharmaceuticals: It serves as a crucial intermediate in the synthesis of drug molecules. Its ability to form stearate esters and amides can modify the lipophilicity of active pharmaceutical ingredients (APIs), thereby improving their absorption, bioavailability, and formulation characteristics. It is notably used in the synthesis of certain antitumor agents and in creating specialized drug delivery systems.
  • Surfactants and Emulsifiers: The long hydrocarbon chain makes Stearoyl Chloride an excellent precursor for synthesizing non-ionic and anionic surfactants. These compounds are indispensable in detergents, cleaning products, personal care items, and industrial formulations for their ability to reduce surface tension and stabilize emulsions.
  • Cosmetics and Personal Care: In cosmetic formulations, Stearoyl Chloride derivatives are used for their emollient and conditioning properties, contributing to the texture and feel of creams, lotions, and other skincare products.
  • Polymers and Materials Science: Stearoyl Chloride can be used to modify polymers, grafting long alkyl chains onto polymer backbones. This process can enhance hydrophobicity, alter surface energy, and improve the mechanical properties of materials, finding applications in advanced coatings and functionalized plastics.
  • Agrochemicals: It can also be employed as an intermediate in the production of certain agrochemicals, contributing to the synthesis of pesticides and crop protection agents.
