Description

Behenoyl Chloride is a high-purity, long-chain fatty acid chloride derivative, a critical reagent for introducing the behenoyl functional group. This compound matters for its role as a versatile building block in the synthesis of specialty esters, amides, and surfactants with tailored properties. It is essential for manufacturers in the pharmaceutical, cosmetic, and specialty polymer industries seeking to create high-performance ingredients and intermediates.

Application

• Pharmaceutical Intermediates: Key starting material for synthesizing active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring lipophilic side chains for enhanced bioavailability.
• Cosmetic & Personal Care Ingredients: Used in the production of emollients, wax esters (e.g., behenyl behenate), and conditioning agents for skin and hair care formulations.
• Polymer & Resin Modification: Acts as a chain extender or modifier in polyamide, polyester, and epoxy resin systems to alter flexibility, hydrophobicity, and thermal stability.
• Surfactant & Lubricant Synthesis: Serves as a precursor for manufacturing cationic, anionic, and nonionic surfactants, as well as specialty lubricants and metalworking fluids.
• Organic Synthesis Reagent: Employed in Friedel-Crafts acylation and other reactions to introduce the docosanoyl moiety into complex organic molecules for research and development.
• Agrochemical Formulations: Intermediate in creating specialized adjuvants, emulsifiers, and slow-release agents for crop protection products.

Quality Control

Our Behenoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and titration methods, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from moisture, strong bases, and oxidizing agents.
