Description

Tosylate Of Pentaethylene Glycol Monobenzyl Ether is a high-purity, functionalized polyethylene glycol derivative designed for advanced chemical synthesis. This compound is valued for its role as a key intermediate in the production of specialized surfactants, phase-transfer catalysts, and functional polymers. It is essential for R&D and manufacturing in the pharmaceutical, agrochemical, and specialty materials sectors seeking to incorporate tailored hydrophilic and reactive properties.

Application

• Pharmaceutical Intermediate: Acts as a crucial building block for synthesizing prodrugs, drug conjugates, and targeted delivery systems.
• Specialty Surfactant Synthesis: Used to manufacture non-ionic surfactants and emulsifiers with specific HLB values for agrochemicals and coatings.
• Polymer Chemistry: Serves as a functional monomer or initiator for creating PEGylated polymers, hydrogels, and responsive materials.
• Phase-Transfer Catalyst (PTC) Precursor: A key starting material for synthesizing quaternary ammonium-type PTCs used in organic synthesis.
• Surface Modification Agent: Employed to functionalize nanoparticles, silica, or other surfaces to impart hydrophilicity and biocompatibility.
• Crosslinking Agent: Utilized in the formulation of specialty adhesives, sealants, and elastomers requiring controlled reactivity.

Quality Control

Our Tosylate Of Pentaethylene Glycol Monobenzyl Ether is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy, to ensure compliance with exacting standards. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
