Description

2,2'-[Oxybis(Ethyleneoxy)]Bisacetyl Dichloride is a high-purity, reactive chemical intermediate featuring a central ether linkage flanked by acid chloride groups. This compound matters for its role as a versatile building block in the synthesis of specialized polymers, surfactants, and pharmaceutical agents, enabling precise molecular architecture. It is primarily needed by R&D chemists and production engineers in the pharmaceutical, agrochemical, and advanced materials industries for creating functionalized polyethylene glycol (PEG) derivatives and other value-added products.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing prodrugs, drug-linkers, and active pharmaceutical ingredients (APIs), particularly for PEGylation strategies to enhance drug solubility and bioavailability.
• Polymer & Resin Synthesis: Used as a difunctional monomer or cross-linking agent in the production of specialty polyesters, polyamides, and other condensation polymers.
• Surfactant & Emulsifier Production: Serves as a precursor for creating novel non-ionic and anionic surfactants with tailored hydrophilic-lipophilic balance (HLB) properties.
• Agrochemical Formulations: Intermediate in the manufacture of advanced herbicides, pesticides, and plant growth regulators requiring specific delivery systems.
• Cross-linking Agent: Employed in coatings, adhesives, and sealants to modify mechanical properties and chemical resistance.
• Bioconjugation Chemistry: Facilitates the covalent attachment of peptides, proteins, or other biomolecules to polymers or solid supports for diagnostic and therapeutic applications.

Quality Control

Our 2,2'-[Oxybis(Ethyleneoxy)]Bisacetyl Dichloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and amines.
