Description

2-Chloropropenoic Acid 1,1-Dimethylethyl Ester is a versatile and reactive chemical intermediate, primarily valued for its role as a protected acrylic acid derivative in advanced organic synthesis. Its structure makes it a crucial building block for introducing the 2-chloroacryloyl moiety into target molecules, enabling the development of specialized polymers, pharmaceuticals, and agrochemicals. This compound is essential for R&D chemists and production specialists in fine chemical, pharmaceutical, and polymer industries seeking to create novel materials and active ingredients with specific functional properties.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a reactive acrylate or α-chloroacrylate functionality.
• Polymer & Resin Modification: Used as a monomer or co-monomer to introduce chlorine and ester groups into polymer backbones, modifying properties like adhesion, weather resistance, and reactivity for specialty coatings and adhesives.
• Agrochemical Synthesis: Acts as a precursor in the manufacture of herbicides, fungicides, and insecticides, where the chloropropenoate group is integral to the biological activity of the final product.
• Fine Chemical Production: Employed in multi-step organic synthesis to construct complex molecules for dyes, flavors, fragrances, and electronic chemicals.
• Cross-linking Agent: Utilized in formulations where its double bond and chlorine atom can participate in cross-linking reactions, enhancing the thermal and mechanical stability of polymeric networks.
• Research & Development: A valuable reagent in academic and industrial R&D labs for exploring new synthetic methodologies and developing novel chemical entities.

Quality Control

Our 2-Chloropropenoic Acid 1,1-Dimethylethyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, purity, and impurity profile determination, to ensure it meets stringent specifications for use in sensitive applications. Certificates of Analysis (COA) documenting identity, purity, and safety parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in opaque or amber glass, or in storage areas shielded from direct light exposure.
