Description

2-[2-[2-[2-[2-[2-(Benzyloxy)Ethoxy]Ethoxy]Ethoxy]Ethoxy]Ethoxy]Ethanol is a high-purity, multi-ethylene glycol derivative featuring a terminal benzyl-protected hydroxyl group. This compound is valued for its role as a versatile, hydrophilic spacer and building block in advanced organic synthesis and material science. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and specialty polymer industries who require precise, functionalized polyether chains to modify solubility, create linkers, or develop novel macromolecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a key building block for synthesizing prodrugs, PEGylated therapeutics, and targeted drug delivery systems, enhancing solubility and bioavailability.
• Bioconjugation Linker: Used to attach drugs, dyes, or other functional molecules to proteins, antibodies, or nanoparticles, leveraging its hydrophilic PEG spacer to reduce immunogenicity.
• Polymer Chemistry: Acts as a functional initiator or monomer in the synthesis of specialized polyethers, non-ionic surfactants, and hydrogels with tailored properties.
• Surface Modification: Employed to create hydrophilic, protein-resistant coatings on medical devices, diagnostic sensors, and chromatographic media.
• Chemical Research: A valuable reagent for organic synthesis, particularly in creating crown ether analogs, phase-transfer catalysts, and complex dendritic structures.
• Formulation Additive: Can be used in specialty formulations where controlled hydrophilicity and a protected hydroxyl group are required.

Quality Control

Our 2-[2-[2-[2-[2-[2-(Benzyloxy)Ethoxy]Ethoxy]Ethoxy]Ethoxy]Ethoxy]Ethanol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

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 nature, the container must be kept sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
