Description

Dansyl-L-Aspartic Acid Di(Cyclohexylammonium) Salt is a high-purity, fluorescently labeled derivative of aspartic acid, widely used as a critical reagent in advanced biochemical research and analytical applications. Its primary value lies in its dansyl fluorophore, which provides excellent sensitivity for detection and quantification in complex matrices. This compound is essential for researchers and manufacturers in the fields of proteomics, peptide synthesis, and analytical chemistry, where precise labeling and trace analysis are required.

Application

• Fluorescent Labeling Agent: Used for the derivatization and subsequent HPLC or capillary electrophoresis analysis of amino acids, peptides, and proteins to enhance detection sensitivity.
• Proteomics Research: Serves as a key reagent in studying protein structure, function, and post-translational modifications via fluorescence tagging.
• Biochemical Assay Development: Employed in the design of sensitive fluorescence-based assays for enzyme activity, substrate specificity, and inhibitor screening.
• Pharmaceutical Analysis: Utilized in the quality control and metabolic studies of peptide-based pharmaceuticals and other bioactive compounds.
• Peptide Synthesis & Modification: Acts as a protected or tagged form of aspartic acid during solid-phase peptide synthesis (SPPS) for introducing fluorescent probes.
• Academic & Industrial R&D: A fundamental tool in life science research for fluorescence microscopy, cell biology studies, and diagnostic method development.

Quality Control

Our Dansyl-L-Aspartic Acid Di(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 specific tests for residual solvents and moisture content. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specification results to ensure traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent degradation from atmospheric moisture. For long-term storage, consider desiccated conditions.
