Description

cis-Vaccenoyl Chloride is a high-purity fatty acid chloride derivative, specifically the acid chloride of cis-vaccenic acid. This compound serves as a critical chemical building block for the synthesis of complex lipids, esters, and other specialty organic molecules. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require precise and reactive intermediates for advanced synthesis.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those with lipid-based delivery systems.
• Lipid Research & Synthesis: A key reagent for creating structured triglycerides, phospholipids, and other complex lipid molecules for biochemical and nutritional studies.
• Agrochemical Production: Employed as an intermediate in the manufacture of specialized pesticides and herbicides that require specific fatty acid chains for efficacy.
• Polymer Modification: Acts as a grafting or coupling agent to introduce long-chain alkyl groups onto polymers, altering surface properties and compatibility.
• Surfactant & Emulsifier Synthesis: Used to produce novel ester-based surfactants with tailored hydrophobic characteristics.
• Cosmetic Ingredient Synthesis: Facilitates the production of specialty esters and emollients used in high-end cosmetic formulations.
• Bioconjugation & Probe Development: Useful in biochemical research for labeling biomolecules with fatty acid tags via amide or ester linkages.

Quality Control

Our cis-Vaccenoyl Chloride is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopic methods, to ensure high chemical purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong bases, oxidizing agents, and moisture.
