Description

Benzenesulfonic Acid, 2-Propenyl Ester is a specialized organic ester of benzenesulfonic acid, serving as a valuable reactive intermediate and functional monomer in advanced chemical synthesis. This compound matters for its ability to introduce sulfonate and polymerizable allyl functionalities into target molecules, enabling the development of materials with tailored properties. It is primarily needed by manufacturers in the polymer, specialty chemical, and pharmaceutical industries for applications ranging from resin modification to the synthesis of functional surfactants and pharmaceutical intermediates.

Application

• Polymer & Resin Modification: Acts as a reactive monomer or cross-linking agent in the production of specialty polymers, coatings, and adhesives to impart sulfonate groups for improved hydrophilicity or ionic character.
• Chemical Intermediate: Serves as a key building block in organic synthesis for pharmaceuticals, agrochemicals, and dyes, leveraging the reactivity of both the sulfonate ester and the allyl group.
• Surface-Active Agent Precursor: Used in the manufacture of specialty surfactants and emulsifiers for niche industrial formulations.
• Photoresist & Electronic Chemicals: May be employed in the formulation of advanced photoresists or other electronic materials where specific solubility and reactivity profiles are required.
• Research & Development: Utilized in academic and industrial R&D labs for exploring new synthetic pathways and material properties.

Quality Control

Our Benzenesulfonic Acid, 2-Propenyl Ester is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including assay and purity verification by chromatographic methods, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting identity, purity, and relevant physical parameters are available upon request 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
