Description

Ethyl 2-(2-(2-(2-Bromoethoxy)ethoxy)ethoxy)acetate is a specialized organic compound featuring a bromo-terminated tetraethylene glycol chain linked to an ethyl acetate group. This unique bifunctional structure makes it a valuable versatile building block for the synthesis of complex molecules, particularly in advanced material science and pharmaceutical research. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, polymer, and specialty chemical industries for creating functionalized polymers, prodrugs, and linker molecules.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing prodrugs, drug conjugates, and active pharmaceutical ingredients (APIs) requiring polyethylene glycol (PEG) linkers.
• Polymer Chemistry: Serves as a functional monomer or initiator for the synthesis of novel PEG-based polymers, hydrogels, and smart materials with tailored properties.
• Bioconjugation: Used to create linker molecules for attaching drugs, dyes, or other functionalities to proteins, antibodies, or nanoparticles.
• Surface Modification: Employed to introduce hydrophilic PEG brushes onto surfaces for anti-fouling or biocompatibility applications.
• Crosslinking Agent: Utilized in the formulation of specialty resins, adhesives, and coatings where controlled reactivity is required.
• Chemical Synthesis: Acts as a protected or activated intermediate in multi-step organic synthesis for academic and industrial research.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong bases and incompatible materials.
