CAS 10199-89-0: NBD-Cl

Description: NBD-Cl, or 7-chloro-4-nitrobenzofurazan, is a chemical compound characterized by its bright yellow color and high reactivity, particularly towards nucleophiles. It features a benzofurazan ring structure, which contributes to its unique optical properties, making it useful in various applications, including fluorescence labeling and as a reagent in organic synthesis. The presence of the nitro and chloro substituents enhances its electrophilic character, allowing it to participate in nucleophilic substitution reactions. NBD-Cl is often employed in the development of fluorescent probes and in the study of biological systems due to its ability to form stable conjugates with amines and thiols. Additionally, it is sensitive to light and moisture, necessitating careful handling and storage conditions to maintain its stability. Overall, NBD-Cl is a valuable tool in chemical research and analytical chemistry, particularly in the fields of biochemistry and molecular biology.
