Description

Dansyl-L-Glutamic Acid Di(Cyclohexylammonium) Salt is a high-purity, derivatized amino acid salt primarily used as a critical reagent and fluorescent probe in advanced biochemical research and analytical method development. Its value lies in its unique dansyl fluorophore, which enables sensitive detection and quantification of amino acids and peptides via HPLC and other chromatographic techniques. This compound is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and analytical chemistry sectors who require reliable, high-quality standards for method validation, proteomics, and metabolic studies.

Application

• HPLC & LC-MS Analytical Standards: Used as a primary reference standard for the quantification of glutamic acid and related compounds in complex matrices.
• Amino Acid Derivatization & Fluorescent Labeling: Serves as a key reagent for pre-column derivatization to enhance the detection sensitivity of amino acids in analytical assays.
• Proteomics & Peptide Research: Employed in the study of protein structure, function, and post-translational modifications via fluorescent tagging.
• Biochemical Assay Development: Utilized in the creation and validation of diagnostic kits and enzymatic assays requiring high-sensitivity fluorescence detection.
• Pharmaceutical Quality Control: Acts as a critical component in the purity testing and method development for amino acid-based active pharmaceutical ingredients (APIs).
• Neuroscience Research: Applied in studies of neurotransmitter pathways, particularly those involving glutamatergic systems.

Quality Control

Our Dansyl-L-Glutamic 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 specifications and test results to ensure traceability and compliance with your research or production 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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and handled under low-light conditions to maintain stability and purity.
