Description

H-Ala-D-Ala-Oh CAS NO 3695-80-5 is a high-purity, synthetic dipeptide consisting of L-alanine and D-alanine residues. This compound is a critical building block and intermediate in the synthesis of complex peptides and peptidomimetics, particularly those of pharmaceutical interest. It is essential for research and development in medicinal chemistry, biochemistry, and the production of advanced active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A key chiral synthon in the synthesis of complex peptide-based drugs and antibiotics.
• Biochemical Research: Used as a substrate or standard in enzymatic studies, proteomics, and metabolic pathway research.
• Peptide Synthesis: Serves as a fundamental building block in solid-phase and solution-phase peptide synthesis (SPPS).
• Antibiotic Research: Crucial for studying and developing novel antibiotics that target bacterial cell wall biosynthesis.
• Protease/Enzyme Studies: Employed in assays to investigate enzyme specificity, inhibition, and kinetics.
• Reference Standard: Used as a high-purity analytical standard in quality control laboratories for HPLC, LC-MS, and NMR.

Quality Control

Our H-Ala-D-Ala-Oh is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation (IR, NMR) to ensure it meets the high standards required for pharmaceutical research and synthesis. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or inert atmosphere.
