Description

Stearoyl Chloride is a versatile fatty acid chloride derivative, specifically the chloride of stearic acid. This compound serves as a critical acylating agent and intermediate in organic synthesis, enabling the efficient introduction of the stearoyl group. It is essential for manufacturers in the pharmaceutical, personal care, and polymer industries who require high-purity reagents for consistent product quality and process reliability.

Application

• Pharmaceutical Synthesis: Key intermediate for producing active pharmaceutical ingredients (APIs) and prodrugs via acylation reactions.
• Surfactant & Emulsifier Production: Used in the manufacture of cationic and amphoteric surfactants for personal care and industrial formulations.
• Polymer Modification: Acts as a chain terminator or modifier in polyamide and polyester synthesis to alter physical properties.
• Lubricant & Grease Additives: Employed in the synthesis of specialized esters and additives that enhance lubricant performance.
• Cosmetic Ingredients: Acylating agent for synthesizing emollients, wax esters, and other conditioning agents in skincare and haircare products.
• Agrochemical Intermediates: Used in the production of certain herbicides and pesticides that require long-chain fatty acid derivatives.
• Laboratory Reagent: Serves as a standard acyl chloride in research and development for organic chemistry applications.
• Textile & Fiber Treatment: Imparts water-repellent and softening characteristics to fabrics and non-woven materials.

Quality Control

Our Stearoyl Chloride is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay (by titration), acid value, and color (APHA) determination, to ensure it meets exacting purity and consistency standards. A Certificate of Analysis (COA) is provided with every shipment, documenting full compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This product is hygroscopic (moisture-sensitive) and reacts vigorously with water, strong bases, and alcohols. Keep the container tightly sealed under an inert atmosphere (nitrogen or argon) to prevent hydrolysis and degradation. Isolate from incompatible materials such as oxidizers and amines.
