Description

Ethyleneglycol-Di-p-Tosylate 95% is a high-purity chemical intermediate primarily used as a versatile alkylating and linking agent in organic synthesis. Its value lies in its ability to introduce ethylene glycol-bridged tosylate functionalities, enabling the controlled construction of complex molecular architectures. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries who require reliable, high-quality building blocks for advanced R&D and production.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for creating prodrugs or molecules with specific solubility profiles.
• Polymer Chemistry: Serves as a cross-linking agent or monomer in the production of specialty polymers, resins, and dendrimers.
• Organic Synthesis: Utilized as a bifunctional alkylating agent to create bridged compounds, macrocycles, and crown ether analogs in research and development.
• Agrochemical Production: Intermediate in the manufacture of certain herbicides, fungicides, and plant growth regulators.
• Material Science: Used in the development of novel organic frameworks and functional materials.
• Chemical Derivatization: Acts as a reagent for protecting groups or for introducing sulfonate ester groups into target molecules.
