Description

1-(5-Dimethylaminonaphthalene 1-Sulfonamido)Decane-10-Trimethylammonium is a specialized cationic surfactant and fluorescent probe derived from dansyl chloride. This compound matters for its unique dual functionality, combining the light-emitting properties of a dansyl fluorophore with the surface-active and membrane-targeting capabilities of a quaternary ammonium salt. It is primarily needed by researchers and manufacturers in the life sciences, particularly for developing advanced diagnostic assays, studying membrane biophysics, and formulating specialized delivery systems where fluorescence tracking is essential.

Application

• Fluorescent Labeling Agent: Used as a sensitive probe for labeling proteins, peptides, and other biomolecules in biochemical research and assay development.
• Membrane Biology Studies: Serves as a fluorescent surfactant to investigate lipid bilayer properties, membrane fluidity, and vesicle formation due to its amphiphilic structure.
• Diagnostic Reagent Intermediate: A key synthetic intermediate in the production of fluorescent diagnostic kits and biosensors.
• Cationic Surfactant for Specialized Formulations: Employed in the formulation of niche personal care or pharmaceutical products where fluorescence or specific charge interactions are required.
• Cell Biology & Microscopy: Acts as a fluorescent tag for cellular imaging, particularly for tracking membrane-associated processes or intracellular delivery.
• Material Science Research: Utilized in the surface modification of nanoparticles or polymers to impart both fluorescence and cationic charge.

Quality Control

Our production of 1-(5-Dimethylaminonaphthalene 1-Sulfonamido)Decane-10-Trimethylammonium adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity for research applications. Each lot undergoes comprehensive analytical characterization. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or an inert atmosphere.
