Description

Vinyl Hydrogen Sulphate is a reactive organosulfur compound primarily used as a versatile intermediate in organic synthesis. Its value lies in its ability to introduce the vinyl sulfate functional group, which can serve as a protected form of an aldehyde or ketone or participate in further polymerization and cross-linking reactions. This makes it a critical material for researchers and manufacturers in the polymer, pharmaceutical, and specialty chemical industries seeking to develop novel materials or complex molecular architectures.

Application

• Polymer Chemistry: Key monomer or co-monomer for synthesizing specialty polymers and resins with specific solubility or reactivity profiles.
• Organic Synthesis Intermediate: Acts as a protected synthon for carbonyl compounds (aldehydes/ketones) in multi-step synthetic routes for pharmaceuticals and agrochemicals.
• Cross-linking Agent: Used in the production of cross-linked polymeric materials, enhancing thermal stability and mechanical properties.
• Surface Modification: Employed to functionalize surfaces or materials with reactive vinyl groups for subsequent grafting or coating applications.
• Chemical Research & Development: Serves as a building block in R&D for exploring new reactions and creating novel chemical entities.
• Production of Sulfate Esters: Used in the synthesis of other sulfate esters for applications in surfactants or biologically active compounds.

Quality Control

Our Vinyl Hydrogen Sulphate is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and purity. Each lot undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full transparency and compliance with your material specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and strong acid/organic solvent properties, store in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C for extended stability. Keep away from incompatible materials such as bases and oxidizing agents.
