Description

cis-13-Docosenoic Anhydride is a high-purity, unsaturated fatty acid anhydride derived from erucic acid. This specialty chemical serves as a versatile intermediate and building block in advanced organic synthesis, offering a reactive site for the introduction of the erucoyl moiety. It is essential for manufacturers and R&D laboratories in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop novel compounds with specific long-chain fatty acid functionalities.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring lipophilic side chains for enhanced bioavailability or targeted delivery.
• Agrochemical Synthesis: Acts as a key precursor for manufacturing herbicides, fungicides, and plant growth regulators with tailored properties.
• Specialty Polymer Modifier: Employed in the production of polyamide resins, polyesters, and other polymers to modify flexibility, hydrophobicity, and thermal stability.
• Lubricant & Grease Additive: Serves as a raw material for synthesizing high-performance esters used in specialized lubricants and metalworking fluids.
• Cosmetic & Personal Care Ingredients: Utilized in the manufacture of emollients, surfactants, and other conditioning agents for skin and hair care formulations.
• Research & Development: A valuable reagent in organic chemistry research for studying fatty acid derivatives and creating novel chemical entities.

Quality Control

Our cis-13-Docosenoic Anhydride 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 consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles 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, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation by atmospheric moisture.
