Description

Vinyl p-Chlorobenzenesulphonate is a specialized organosulfur compound used as a key reactive intermediate in advanced organic synthesis. Its primary value lies in its vinyl sulfonate ester functionality, which enables efficient cross-coupling and polymerization reactions under controlled conditions. This chemical is particularly relevant for researchers and manufacturers in the pharmaceutical, agrochemical, and polymer industries seeking to introduce sulfonate ester groups or create novel functional materials.

Application

• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for sulfonamide-based drugs.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides where the p-chlorobenzenesulfonyl moiety is required.
• Polymer & Material Science: Acts as a monomer or cross-linking agent in the development of specialty polymers, ion-exchange resins, and functional coatings.
• Organic Synthesis Reagent: Employed in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) as an electrophilic coupling partner.
• Chemical Research: Utilized in academic and industrial R&D for exploring new synthetic methodologies and creating complex molecular architectures.
• Dye & Pigment Manufacturing: Functions as an intermediate in the synthesis of sulfonated dyes and colorants.

Quality Control

Every batch of Vinyl p-Chlorobenzenesulphonate is produced and analyzed under strict quality management protocols. We ensure high purity and consistency through comprehensive analytical techniques including HPLC, GC, and NMR spectroscopy. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and impurity profiles to meet your specific R&D or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation by atmospheric moisture. Keep away from heat, sparks, and open flame.
