Description

Heneicosanoyl Chloride CAS NO 77582-61-7 is a high-purity, long-chain fatty acid chloride derivative. This compound serves as a critical building block in organic synthesis, enabling the introduction of the heneicosanoyl moiety for the creation of specialized esters, amides, and polymers. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require precise, high-quality intermediates for advanced material development.

Application

• Pharmaceutical Intermediate: Key reagent in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly for lipid-conjugation strategies to enhance bioavailability.
• Agrochemical Synthesis: Used in the production of specialized pesticides, herbicides, and plant growth regulators that require long-chain fatty acid components.
• Polymer & Material Science: Acts as a monomer or modifying agent in the creation of polyesters, polyamides, and surface coatings to impart specific hydrophobic or rheological properties.
• Lubricant & Surfactant Additive: Employed in the synthesis of ester-based lubricant additives and specialty surfactants for high-performance formulations.
• Biochemical Research: Utilized in lipidomics research and for the chemical modification of biomolecules, such as peptides and sugars, to study structure-activity relationships.
• Flavor & Fragrance Industry: Serves as a precursor for the synthesis of specific macrocyclic musk compounds and flavor esters.

Quality Control

Our Heneicosanoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling by GC/HPLC, to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its moisture-sensitive and light-sensitive nature. Keep away from strong bases, oxidizers, and sources of ignition.
