Description

Stearonitrile is a high-purity, long-chain fatty nitrile with the CAS registry number 638-65-3, serving as a versatile intermediate in organic synthesis. Its linear C18 structure provides a valuable hydrophobic building block for creating surfactants, lubricants, and specialty polymers. This compound is essential for manufacturers in the chemical, agrochemical, and material science industries seeking to develop performance additives and functional molecules.

Application

• Chemical Intermediate: A key precursor in the synthesis of primary amines (e.g., stearyl amine) via hydrogenation and for producing quaternary ammonium compounds.
• Surfactant & Detergent Manufacturing: Used to create cationic and amphoteric surfactants for fabric softeners, personal care products, and industrial cleaners.
• Lubricant & Fuel Additives: Acts as a starting material for manufacturing friction modifiers, corrosion inhibitors, and anti-wear agents.
• Polymer Industry: Employed as a comonomer or modifier in the production of polyamides, polyesters, and other specialty polymers to alter surface properties.
• Agrochemical Synthesis: Serves as an intermediate in the production of certain herbicides, pesticides, and plant growth regulators.
• Pharmaceutical Intermediates: Used in controlled syntheses for active pharmaceutical ingredients (APIs) and other fine chemicals.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new organic reactions and material properties.
