Description

Alpha, ω-Dipropionic Acid Hexaethylene Glycol is a high-purity, functionalized polyethylene glycol derivative designed for advanced material synthesis. This compound is valued for its bifunctional reactivity, featuring terminal carboxylic acid groups linked by a flexible, hydrophilic hexaethylene glycol spacer. It serves as a critical building block for researchers and manufacturers in the pharmaceutical and specialty polymer industries, enabling the creation of precisely engineered conjugates, hydrogels, and functional materials.

Application

• Pharmaceutical Conjugation: A key linker for the synthesis of prodrugs, antibody-drug conjugates (ADCs), and peptide modifications, leveraging its water-solubility and biocompatibility.
• Polymer Chemistry: Serves as a difunctional monomer or chain extender for producing tailored polyesters, polyamides, and other step-growth polymers with controlled hydrophilicity.
• Crosslinking Agent: Used in the formulation of hydrogels and crosslinked networks for biomedical applications such as drug delivery systems and tissue engineering scaffolds.
• Surface Modification: Facilitates the functionalization of nanoparticles, quantum dots, and other material surfaces to improve solubility, stability, and targeting capabilities.
• Specialty Surfactants & Lubricants: Acts as an intermediate for synthesizing high-performance, biodegradable surfactants and lubricants with unique solubility profiles.

Quality Control

Our Alpha, ω-Dipropionic Acid Hexaethylene Glycol is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial applications. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request.

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