Description

Dansyl-Dl-Leucine Cyclohexylammonium Salt is a high-purity, derivatized amino acid salt primarily used as a key analytical reagent and synthetic intermediate. Its value lies in the dansyl (5-dimethylaminonaphthalene-1-sulfonyl) group, which provides strong fluorescence and UV activity, making it essential for sensitive detection and labeling applications. This compound is critically needed by research institutions, pharmaceutical developers, and analytical laboratories working on peptide synthesis, amino acid analysis, and fluorescence-based assay development.

Application

• Fluorescent Labeling Agent: Used to tag peptides, proteins, and amino acids for detection in HPLC, capillary electrophoresis, and other chromatographic techniques.
• Analytical Reference Standard: Serves as a critical standard for calibrating instruments and validating methods in amino acid analysis and proteomics research.
• Pharmaceutical Intermediate: Employed in the synthesis and development of novel peptide-based therapeutics and diagnostic agents.
• Biochemical Research: Utilized in enzyme studies, receptor-ligand binding assays, and other life science research requiring fluorescent probes.
• Derivatization Reagent: Enhances the detectability of low-concentration amino acids in complex biological matrices for accurate quantification.

Quality Control

Our Dansyl-Dl-Leucine Cyclohexylammonium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and loss on drying for moisture content. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specification results to ensure compliance with your research and development requirements.

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.
