Description

Arachidoyl Chloride is a high-purity, long-chain fatty acid chloride derivative, essential for introducing the arachidoyl (C20) moiety into complex molecules. Its primary value lies in its high reactivity as an acylating agent, enabling precise synthesis in advanced research and industrial-scale production. This compound is critically needed by manufacturers and R&D teams in the pharmaceutical, agrochemical, and specialty polymer sectors for creating surfactants, lubricant additives, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediates: Key building block for the synthesis of prodrugs, lipid conjugates, and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of specialized pesticides, herbicides, and plant growth regulators requiring long-chain fatty acid components.
• Polymer & Resin Modification: Acts as a monomer or modifier in the creation of polyamides, polyesters, and other specialty polymers to enhance hydrophobicity and stability.
• Surfactant & Lubricant Additives: Serves as a precursor for synthesizing high-performance surfactants, emulsifiers, and extreme-pressure lubricant additives.
• Bioconjugation & Lipid Research: Employed in biochemical research for labeling, cross-linking, and modifying biomolecules such as peptides and steroids.
• Cosmetic Ingredient Synthesis: Used in the manufacture of emollients, wax esters, and other long-chain derivatives for personal care formulations.

Quality Control

Our Arachidoyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each 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 place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases, alcohols, and water.
