Description

2-Chloroacrylic Acid is a versatile and reactive organic acid ester intermediate, characterized by its α-chloro-substituted acrylic structure. This compound is valued for its bifunctional reactivity, serving as a key building block in the synthesis of specialty polymers, pharmaceuticals, and agrochemicals. It is primarily sought by R&D chemists and process engineers in the fine chemical, pharmaceutical, and advanced material manufacturing sectors for introducing functional groups and modifying polymer backbones.

Application

• Pharmaceutical Intermediates: A crucial precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a reactive vinyl chloride moiety for further functionalization.
• Polymer & Resin Modification: Used as a co-monomer or cross-linking agent to impart specific properties like adhesion, chemical resistance, or reactivity into acrylic and vinyl polymers.
• Agrochemical Synthesis: Serves as a building block for manufacturing herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: Employed in organic synthesis for creating complex molecules used in dyes, pigments, and specialty chemicals.
• Adhesive & Coating Formulations: Incorporated to enhance the performance characteristics of industrial adhesives and protective coatings.
• Chemical Research & Development: A valuable reagent for exploring new synthetic pathways and material science applications in academic and industrial labs.

Quality Control

Our 2-Chloroacrylic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by titration and impurity profile analysis via GC/HPLC, to ensure it meets precise specifications. A Certificate of Analysis (COA) documenting purity, identity, and key physical parameters is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and strong acid/organic solvent properties, the container must be kept tightly sealed and separated from bases, oxidizing agents, and sources of ignition.
