Description

Cyclo(-Asp-Asp) CAS NO 35309-53-6 is a cyclic dipeptide, also known as a diketopiperazine (DKP), formed from two aspartic acid residues. This compound serves as a crucial pharmaceutical intermediate and a valuable research chemical for studying peptide conformation and biological activity. It is primarily utilized by pharmaceutical manufacturers and biotechnology research organizations involved in drug discovery and development.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of more complex peptide-based drugs and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a model compound in studies of peptide folding, cyclization kinetics, and structure-activity relationships (SAR).
• Protease Inhibitor Scaffold: Serves as a core structure for developing enzyme inhibitors due to its constrained cyclic conformation.
• Cell Culture & Media Supplement: Potential application as a component in specialized cell culture media for certain biological studies.
• Reference Standard: Employed as a high-purity analytical standard in quality control laboratories for method development and validation.

Quality Control

Our Cyclo(-Asp-Asp) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for pharmaceutical and research applications. Certificates of Analysis (COA) detailing all specifications and test results are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
