What are the main uses of 2,6-difluorobenzenesulfonamide?

2% 2C6-diethylaminofluorescein succinimide ester, often referred to as FITC-SE, its main uses are as follows.

This substance is an extremely important fluorescent labeling reagent in the field of biochemical research. It is widely used in the labeling operation of biological macromolecules such as proteins, peptides and nucleic acids. Taking protein labeling as an example, its carboxyl group can be covalently linked to the amino group of the protein through a condensation reaction. In this way, the protein is labeled with fluorescence, which is like a "sign" for the protein to hang up and shine. In follow-up experiments, researchers can easily track the whereabouts of proteins with the help of fluorescence detection equipment, providing clear insight into their distribution in cells, such as what organelles are enriched in and how they are transported within cells over time.

In the field of immunoassay, FITC-SE also plays a key role. In enzyme-linked immunosorbent assay (ELISA), immunofluorescent histochemistry and other experiments, labeling antibodies is a core step. By labeling FITC-SE on a specific antibody, the antibody precisely binds to the target antigen with its specific recognition ability. Once combined, due to the fluorescence properties of FITC-SE, researchers can sensitively and accurately detect the presence of antigens with instruments such as fluorescence microscopy or flow cytometry, so as to achieve qualitative and quantitative analysis of specific antigens in biological samples.

In cell biology research, FITC-SE can be used for cell tracing. Labeling it on the surface of cells or introducing it into cells is like installing a "locator" on cells. When cells migrate and differentiate in vivo or in vitro, researchers can continuously track cell dynamics based on the fluorescence emitted by FITC-SE, providing key data support for in-depth investigation of cell physiological and pathological processes.

In conclusion, 2% 2C6 -diethylaminofluorescein succinimide ester plays an indispensable role in many scientific research fields due to its unique fluorescent labeling characteristics, assisting researchers in continuously exploring the mysteries of life.

What is the production method of 2,6-difluorobenzenesulfonamide?

2% 2C6-diethylamino-fluorone (2,6-Diethylamino-fluorone) is an analytical reagent, which is often used in the spectrophotometric determination of metal ions. The preparation method is as follows:

First, resorcinol is used as the starting material. The condensation reaction between resorcinol and phthalic anhydride is carried out at an appropriate temperature (about 180-200 ℃) in the presence of concentrated sulfuric acid or anhydrous dehydrating agents such as zinc chloride. This step of the reaction generates the parent structure of fluorescent ketones. The reaction equation is roughly: resorcinol + phthalic anhydride $\ stackrel {dehydrating agent, 180 - 200 ℃}{→}$ fluorescent ketone intermediate + water.

Next, the above fluorescent ketone intermediates are ethaminated. In a suitable organic solvent (such as N, N-dimethylformamide, DMF), an appropriate amount of ethylamine is added, and under heating conditions (about 80-100 ° C), the fluorescent ketone intermediate is substituted with ethylamine, and two ethylamino groups are introduced at specific positions in the structure of the fluorescent ketone to obtain 2,6-diethylamino fluorone. The reaction formula can be simply expressed as: Fluorescent ketone intermediate + 2 ethylamine $\ stackrel {DMF, 80-100 ℃}{→}$ 2,6-diethylamino fluorone + by-products (may be small molecule amine salts, etc.). After the

reaction is completed, the impurities in the reaction system are removed by conventional separation and purification methods, such as cooling crystallization, filtration, recrystallization (suitable solvents such as ethanol can be selected) and column chromatography separation, and finally high-purity 2,6-diethylamino fluorone products are obtained.
