Description

Dalargin Acetate is a synthetic peptide derivative of the endogenous opioid peptide Leu-enkephalin, known for its biological activity. This compound is of significant interest in advanced pharmaceutical research and development, particularly in the study of neuropeptide systems and potential therapeutic applications. It is primarily utilized by research institutions, pharmaceutical developers, and biotechnology companies engaged in neuroscience, analgesia research, and peptide-based drug discovery.

Application

• Pharmaceutical R&D: Serves as a key reference standard and active pharmaceutical ingredient (API) in preclinical research for neurological and pain management studies.
• Biochemical Research: Used as a tool compound to investigate opioid receptor interactions, signal transduction pathways, and the physiological role of enkephalins.
• Peptide Chemistry Studies: Employed in methodological development for peptide synthesis, purification, and stability testing.
• Analytical Standard: Functions as a high-purity calibrant in chromatographic (HPLC, UPLC) and mass spectrometric analyses for quality control and method validation.

Quality Control

Our Dalargin Acetate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identity confirmation by spectroscopic methods (IR, MS), purity determination by HPLC, and specific tests for related substances and residual solvents. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure traceability and compliance with your research or development specifications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic (moisture-sensitive) nature, the container should be allowed to equilibrate to room temperature before opening to prevent condensation. For long-term storage, consider under an inert atmosphere.
