Overview
Diaspartic acid, or dipeptide aspartyl-aspartate, is a dimer formed from two aspartic acid molecules. It plays a significant role in biochemical research and peptide synthesis due to its structural properties. This compound is often utilized as a building block in the pharmaceutical industry for developing more complex peptides and proteins. Its synthesis typically involves the condensation of aspartic acid molecules under controlled conditions. The purity and quality of diaspartic acid are critical for its applications, making it essential for buyers to source it from reputable suppliers.
Physical and Chemical Properties
Diaspartic acid presents as a white to off-white crystalline powder with a molecular weight of 248.19 g/mol. It is soluble in water and slightly soluble in ethanol, which makes it suitable for various aqueous applications. The compound decomposes at temperatures around 210-215°C, and it is hygroscopic, requiring careful storage to prevent moisture absorption. The molecular formula C8H12N2O7 reflects its composition as a dimer of aspartic acid. Its stability under recommended storage conditions ensures its utility in long-term research and industrial applications. However, exposure to extreme temperatures or humidity should be avoided to maintain its integrity.
Main Applications
Diaspartic acid is primarily used in biochemical research and peptide synthesis. Its role as a dipeptide makes it valuable for studying peptide bonds and protein structures. Researchers often employ it to investigate enzymatic processes and molecular interactions. In the pharmaceutical industry, diaspartic acid serves as a precursor for synthesizing more complex peptides and therapeutic agents. Its applications extend to cosmetic formulations, where it may act as a moisturizing agent or stabilizer. The compound's versatility underscores its importance in both academic and industrial settings.
Safety and Storage
Handling diaspartic acid requires standard laboratory precautions to ensure safety. Avoid inhalation of dust and direct contact with skin or eyes. Personal protective equipment, such as gloves and goggles, should be worn during use. In case of exposure, rinse affected areas thoroughly with water. Storage conditions are critical to maintaining the compound's stability. Keep diaspartic acid in a cool, dry place, away from light and moisture. Sealed containers are recommended to prevent degradation. Proper storage not only preserves the compound's efficacy but also extends its shelf life for research and industrial use.
B2B Procurement Guide
When procuring diaspartic acid, prioritize suppliers who provide detailed certificates of analysis (CoA) to verify purity and composition. Bulk purchases may offer cost advantages, but ensure the supplier can meet your quality and quantity requirements consistently. Consider the compound's intended use when selecting a grade. Research-grade diaspartic acid may suffice for laboratory experiments, while pharmaceutical-grade material is essential for therapeutic applications. Always confirm the CAS number and molecular formula to avoid discrepancies. Establishing long-term relationships with reliable suppliers can streamline procurement and ensure consistent quality.
