Description

12-n-Methyl-7-Nitrobenzo-2-Oxa-1,3-Diazolamino Stearate is a specialized fluorescent labeling reagent, a derivative of the widely used 7-nitrobenz-2-oxa-1,3-diazole (NBD) chromophore. This compound matters for its ability to covalently tag biomolecules and polymers, providing a sensitive and stable fluorescent probe for detection and analysis. It is primarily needed by researchers and manufacturers in the life sciences, polymer chemistry, and analytical reagent sectors for applications in fluorescence microscopy, flow cytometry, and material science.

Application

• Fluorescent Labeling of Biomolecules: Covalent conjugation to proteins, peptides, lipids, and nucleic acids for tracking and visualization in biological assays.
• Polymer and Material Science: Incorporation into polymers or surfaces as a fluorescent tracer to study material properties, distribution, and degradation.
• Analytical Chemistry Reagent: Used as a derivatization agent in High-Performance Liquid Chromatography (HPLC) and other separation techniques for the sensitive detection of amines and thiols.
• Diagnostic Kit Development: A key component in the formulation of fluorescent probes and test kits for clinical and research diagnostics.
• Cell Biology and Imaging: Staining of cellular components for real-time imaging and analysis using fluorescence microscopy and spectroscopy.
• Sensor Development: Integration into chemical sensors and biosensors where a fluorescent signal change indicates the presence of a specific analyte.

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 desiccated environment to prevent degradation. For long-term stability, consider storage under an inert atmosphere.
