Description

Dansyl-Dl-Aspartic Acid Di(Cyclohexylammonium) Salt is a high-purity, derivatized amino acid salt primarily used as a critical reagent in advanced analytical and biochemical research. Its core value lies in its dansyl fluorophore, which enables highly sensitive detection and quantification of amino acids and peptides via fluorescence spectroscopy and chromatography. This compound is essential for researchers and quality control laboratories in the pharmaceutical, biotechnology, and analytical chemistry sectors who require precise fluorescent labeling for method development, proteomics, and metabolic studies.

Application

• Fluorescent Derivatization Agent: Used for pre-column or post-column derivatization of amino acids in High-Performance Liquid Chromatography (HPLC) and Liquid Chromatography-Mass Spectrometry (LC-MS) to enhance detection sensitivity and selectivity.
• Biochemical Research: Serves as a standard or reagent in proteomics for studying protein structure, function, and amino acid metabolism.
• Pharmaceutical Analysis: Employed in the development and validation of analytical methods for the quantification of amino acids in drug substances, excipients, and finished products.
• Diagnostic Kit Manufacturing: A key component in the formulation of diagnostic kits and assays that utilize fluorescence-based detection principles.
• Peptide Synthesis & Labeling: Used to introduce a fluorescent tag onto peptides or aspartic acid residues for tracking, purification, or interaction studies.
• Food & Nutraceutical Analysis: Applied in the accurate measurement of free amino acid content in food products, supplements, and nutritional formulations.

Quality Control

Our Dansyl-Dl-Aspartic Acid Di(Cyclohexylammonium) Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity assessment and spectroscopic methods for identity confirmation, to ensure it meets the high standards required for research and analytical applications. Certificates of Analysis (COA) with detailed batch-specific data are available upon request to support your regulatory and quality assurance needs.

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) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and away from direct light exposure to maintain stability and purity.
