In the intricate world of chemical synthesis, specific building blocks and intermediates are crucial for constructing complex molecules with desired properties. D-Leucylglycine, identified by its CAS number 997-05-7, is one such versatile compound that plays a significant role in various synthetic pathways, particularly within the pharmaceutical and organic chemistry sectors.

D-Leucylglycine is a dipeptide, meaning it is composed of two amino acid residues linked by a peptide bond. In this case, it is formed from D-leucine and glycine. The presence of D-leucine, an unnatural isomer of leucine, is noteworthy. Incorporating D-amino acids into synthetic strategies can lead to molecules with enhanced stability, particularly against enzymatic degradation, which is a critical consideration in drug development for prolonging a compound's half-life in biological systems. Researchers looking to buy D-Leucylglycine often do so with these stability-enhancing properties in mind.

As a pharmaceutical intermediate, D-Leucylglycine serves as a fundamental unit for building more elaborate drug candidates. Its specific structure allows it to be strategically incorporated into larger molecules through various coupling reactions. For instance, in peptide synthesis, it can be used as a pre-formed dipeptide unit to streamline the process and introduce specific stereochemical features. The high purity (≥98%) typically offered by manufacturers ensures that these synthetic reactions proceed cleanly, minimizing unwanted byproducts.

Beyond its direct use in pharmaceutical synthesis, D-Leucylglycine finds applications in broader organic synthesis. Its functional groups – the amine, carboxylic acid, and amide linkages – offer multiple points for chemical modification and reaction. This makes it a valuable reagent for academic research exploring novel chemical methodologies or for the synthesis of specialized organic materials. The availability from suppliers as a white powder solid, with clear chemical identifiers like H-D-LEU-GLY-OH, simplifies its integration into experimental protocols.

When considering the purchase of D-Leucylglycine, understanding its physical and chemical properties is essential for proper handling and reaction planning. Its typical storage at -20°C highlights its sensitivity to temperature, necessitating careful handling throughout the supply chain. Manufacturers and suppliers play a crucial role in ensuring that these conditions are met, from production to delivery.

For chemical synthesis professionals, securing a reliable source for D-Leucylglycine is paramount. Exploring options from reputable manufacturers, particularly those in regions with robust chemical production capabilities like China, can offer a balance of quality and cost-effectiveness. Requesting a quote for this essential building block ensures access to its synthetic potential for your next project. By understanding its role and properties, chemists can effectively leverage D-Leucylglycine to drive innovation in molecular design.
