Description

Ethyl 3-(3-Chlorosulfonylphenyl)Acrylate is a high-value, multi-functional chemical intermediate featuring both an acrylate ester and a reactive chlorosulfonyl group. This unique structure makes it a critical building block for synthesizing advanced materials and fine chemicals, enabling the introduction of polymerizable and sulfonamide functionalities. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for creating novel active ingredients and functional monomers.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those requiring sulfonamide or sulfonylurea pharmacophores.
• Agrochemical Synthesis: Used to develop advanced herbicides, fungicides, and insecticides with enhanced activity and selectivity.
• Polymer & Material Science: Serves as a functional monomer for creating specialty polymers, coatings, and resins with specific surface-active or cross-linking properties.
• Liquid Crystal & OLED Materials: A valuable building block for synthesizing advanced organic electronic materials and display components.
• Dye & Pigment Manufacturing: Intermediate in the production of high-performance, sulfonated dyes and organic pigments.
• Cross-linking Agent: Utilized in formulations where its dual functionality can create polymer networks with tailored properties.

Quality Control

Every batch of Ethyl 3-(3-Chlorosulfonylphenyl)Acrylate is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) confirming identity, purity, and impurity profiles is available for each lot upon request.

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, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
