Description

Diammonium Maleate CAS NO 23705-99-9 is the diammonium salt of maleic acid, a versatile chemical intermediate with significant utility in organic synthesis. Its primary value lies in its role as a precursor for the production of specialty chemicals, polymers, and other maleate derivatives. This compound is particularly relevant for manufacturers in the polymer, resin, and fine chemical industries seeking reliable raw materials for their production processes.

Application

• As a key monomer or co-monomer in the synthesis of specialty polymers and resins.
• As a chemical intermediate in the production of other maleate salts and esters.
• In the formulation of cross-linking agents for coatings and adhesives.
• As a buffering agent or pH adjuster in specific industrial processes.
• In the synthesis of pharmaceutical intermediates and active ingredients.
• For research and development purposes in organic chemistry laboratories.
• Potential use in water treatment formulations as a chelating agent.
• As a starting material for the production of food-grade additives (subject to appropriate purity and regulatory compliance).

Quality Control

Our Diammonium Maleate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. We offer various grades, including technical and higher purity options, to meet diverse industrial requirements. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and impurity profiles are 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, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can lead to caking or degradation. Keep away from incompatible materials such as strong oxidizing agents.
