Description

2-(2-(2-Chloroethoxy)Ethoxy)Acetic Acid is a versatile bifunctional organic compound featuring both a carboxylic acid and a chlorinated polyether chain. This unique structure makes it a valuable intermediate for the synthesis of complex molecules, particularly in the pharmaceutical and specialty chemical sectors. It is essential for researchers and manufacturers developing active pharmaceutical ingredients (APIs), functional polymers, and advanced surfactants where precise molecular architecture is required.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of complex drug molecules, particularly for introducing hydrophilic, polyether-linked side chains.
• Polymer Chemistry: Used as a monomer or cross-linking agent for producing functionalized polymers and hydrogels with tailored properties.
• Surfactant & Detergent Synthesis: Serves as a precursor for anionic and nonionic surfactants with specific solubility and emulsification characteristics.
• Ligand & Chelating Agent Production: Functionalized to create polyether-based ligands for metal catalysis or chelation applications.
• Organic Synthesis Reagent: Employed in peptide coupling and other carboxyl-activation reactions due to its reactive acid group.
• Bioconjugation Linker: Useful in attaching molecules to proteins, antibodies, or other biomolecules for diagnostic and therapeutic applications.

Quality Control

Our 2-(2-(2-Chloroethoxy)Ethoxy)Acetic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation. Keep away from strong acids and organic solvents.
