Description

11-Eicosenoyl Chloride is a high-purity, long-chain fatty acid chloride derivative, a critical reagent for introducing the eicosenoyl moiety into target molecules. Its primary value lies in its role as a versatile acylating agent, enabling the synthesis of specialized esters, amides, and polymers with tailored properties. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, particularly for lipid conjugation, polymer modification, and the development of bioactive compounds.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing lipid-drug conjugates, prodrugs, and active pharmaceutical ingredients (APIs) requiring long-chain fatty acid modifications.
• Agrochemical Synthesis: Used in the production of specialized pesticides, herbicides, and plant growth regulators where the long alkyl chain influences bioavailability and activity.
• Polymer & Material Science: Acts as a monomer or modifying agent for creating polyesters, polyamides, and surface coatings to alter hydrophobicity, flexibility, or biocompatibility.
• Bioconjugation & Probe Development: Essential for labeling biomolecules (proteins, peptides) with fluorescent or other reporter tags via stable amide or ester linkages.
• Lubricant & Surfactant Additive Precursor: Serves as a raw material for synthesizing high-performance ester-based lubricants and specialty surfactants.
• Cosmetic & Personal Care Ingredients: Employed in the manufacture of emollients, wax esters, and other conditioning agents for skin and hair care formulations.

Quality Control

Our 11-Eicosenoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC, GC) and spectroscopic methods (IR, NMR), to ensure high chemical purity and identity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon). Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed and handled under dry conditions to prevent hydrolysis. Keep away from strong bases, oxidizing agents, and alcohols.
