Description

L-Aspartic Acid, 4-Monoanhydride With Phosphoric Acid (9Ci) is a specialized biochemical intermediate, also known as aspartyl phosphate. This compound is a key activated derivative of aspartic acid, where the carboxylic acid group is esterified with phosphoric acid, making it a crucial high-energy phosphate donor in enzymatic reactions. It is primarily sought after by research institutions and manufacturers in the pharmaceutical and biotechnology sectors for its role in studying and synthesizing peptides, enzyme substrates, and metabolic pathways. Its precise chemical structure makes it an essential building block for advanced biochemical research and process development.

Application

• Biochemical Research: Used as a phosphorylated amino acid analog and a high-energy phosphate donor in enzymatic studies, particularly for kinases and ATP-dependent processes.
• Pharmaceutical Intermediates: Serves as a critical precursor in the synthesis of peptide-based drugs and prodrugs where a phospho-aspartate moiety is required.
• Enzyme Substrate Development: Employed in the development and testing of assays for enzymes like aspartokinase and other phosphotransferases.
• Metabolic Pathway Analysis: A valuable tool for investigating the urea cycle and amino acid metabolism in both in vitro and in vivo research models.
• Nutraceutical Synthesis: Potential intermediate in the development of specialized nutrients and bioactive compounds.
• Academic & Industrial R&D: Essential for universities and corporate R&D labs focusing on bioorganic chemistry, medicinal chemistry, and molecular biology.
