Description

Butanedioic Acid, Hydroxy-, Bis(2-Hydroxyethyl)Ester is a versatile diester derivative of succinic acid, valued for its bifunctional hydroxyl and ester groups. This chemical structure makes it a valuable intermediate and functional additive, offering properties such as plasticization, cross-linking, and solubilization. It is primarily sought by manufacturers in the polymer, coatings, and specialty chemical industries for applications ranging from resin modification to personal care formulations.

Application

• As a reactive intermediate or monomer in the synthesis of polyester resins and alkyd resins for coatings and adhesives.
• As a plasticizer or co-monomer to modify the flexibility and processing characteristics of various polymers.
• In the formulation of UV-curable resins and inks, where its hydroxyl groups can participate in cross-linking reactions.
• As a building block for specialty surfactants and emulsifiers used in industrial and cleaning applications.
• As a component in personal care products, such as hair sprays and setting lotions, functioning as a film-forming agent or modifier.
• In the production of water-based dispersions and pigment preparations for the paints and coatings industry.

Quality Control

Our Butanedioic Acid, Hydroxy-, Bis(2-Hydroxyethyl)Ester is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key specifications are available for every shipment to support your quality assurance protocols.

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 tightly sealed after initial use to minimize moisture absorption. Keep away from strong alkalis and incompatible materials.
