Description

Ethylenesulfate is a versatile and highly reactive cyclic sulfate ester, a key building block in organic synthesis and advanced material science. Its primary value lies in its ability to act as a bifunctional alkylating and sulfonating agent, enabling the efficient introduction of 2-hydroxyethylsulfonate groups under mild conditions. This makes it an indispensable intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop novel compounds with enhanced properties.

Application

• Pharmaceutical Intermediate: Critical for synthesizing active pharmaceutical ingredients (APIs), particularly in the development of sulfonate-containing drugs, prodrugs, and bioconjugates.
• Polymer & Material Science: Used as a cross-linking agent or monomer to produce specialty polymers, hydrogels, ion-exchange resins, and coatings with tailored solubility and ionic characteristics.
• Agrochemical Synthesis: Serves as a key precursor in creating novel herbicides, fungicides, and plant growth regulators that require the 2-hydroxyethylsulfonate functional group.
• Electrolyte Additive: Employed in the formulation of advanced lithium-ion battery electrolytes to improve cathode stability and cycle life.
• Organic Synthesis Reagent: A valuable reagent for introducing sulfonate ester groups in complex molecule construction, including natural product synthesis and fine chemical manufacturing.
• Surface Modification: Utilized to functionalize surfaces of materials like silica, polymers, or metals to alter wettability, adhesion, or biocompatibility.

Quality Control

Our Ethylenesulfate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identification (IR, NMR), and impurity profiling, to ensure it meets the high-purity standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability, consistency, and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent decomposition. Keep away from strong bases and reducing agents.
