Description

Dansyl-L-Valine Cyclohexylammonium is a high-purity, protected amino acid derivative where the dansyl group serves as a fluorescent label and the cyclohexylammonium salt enhances stability and solubility. This compound is critical for advanced research and development in analytical chemistry and life sciences, enabling precise detection and quantification. It is primarily needed by pharmaceutical R&D teams, analytical laboratories, and manufacturers of diagnostic reagents for applications in fluorescence labeling, peptide synthesis, and chromatographic analysis.

Application

• Fluorescent Labeling Agent: Used as a derivatization reagent in HPLC and LC-MS for the sensitive detection and quantification of amino acids, peptides, and amines.
• Biochemical Research: Serves as a key intermediate or standard in proteomics, enzymology, and metabolic pathway studies.
• Pharmaceutical Development: Employed in the synthesis and analysis of novel peptide-based drug candidates and active pharmaceutical ingredients (APIs).
• Diagnostic Reagent Manufacturing: A component in the production of high-sensitivity diagnostic kits and assays.
• Chromatographic Standards: Acts as a certified reference material (CRM) for method development and calibration in analytical laboratories.
• Peptide Synthesis: Used as a protected valine derivative in solid-phase and solution-phase peptide synthesis protocols.

Quality Control

Our Dansyl-L-Valine Cyclohexylammonium is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and moisture content, to ensure it meets the high standards required for research and analytical applications. Certificates of Analysis (COA) with complete batch data are provided to guarantee traceability and consistency.

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 an inert atmosphere.
