Description

Allyl Chlorooxoacetate is a reactive bifunctional ester and acid chloride derivative, serving as a versatile building block in advanced organic synthesis. Its unique structure enables efficient introduction of both an allyl ester and a highly reactive acyl chloride moiety into target molecules. This compound is particularly valuable for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop novel compounds and functional materials.

Application

• Pharmaceutical Intermediate: Key synthon for the preparation of active pharmaceutical ingredients (APIs), especially those requiring allyl-protected carboxylic acids or subsequent deprotection strategies.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators that incorporate specific ester and acid chloride functionalities.
• Polymer & Material Science: Acts as a monomer or cross-linking agent for the synthesis of specialty polymers, coatings, and resins with tailored properties.
• Peptide Chemistry: Employed in peptide synthesis for the temporary protection of carboxylic acid groups via allyl ester formation.
• Ligand & Catalyst Development: Useful precursor for creating complex organic ligands and organometallic catalysts used in asymmetric synthesis.
• Fine Chemical Production: Intermediate in the multi-step synthesis of complex fragrance, flavor, and dye molecules.

Quality Control

Our Allyl Chlorooxoacetate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (IR, NMR), to ensure high purity and consistency. A Certificate of Analysis (COA) detailing identity, purity, 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, well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, amines, and alcohols.
