COUMARIN-6-SULFONYL CHLORIDE

Description:

Coumarin-6-sulfonyl chloride, with the CAS number 10543-42-7, is a chemical compound characterized by its sulfonyl chloride functional group attached to a coumarin moiety. This compound typically appears as a solid or crystalline substance and is known for its fluorescent properties, making it useful in various applications, including as a fluorescent probe in biological and chemical research. The presence of the sulfonyl chloride group enhances its reactivity, allowing it to participate in nucleophilic substitution reactions, which can be exploited for further chemical modifications. Coumarin derivatives are often studied for their potential applications in pharmaceuticals, dyes, and as intermediates in organic synthesis. Additionally, the compound's solubility in organic solvents and its stability under standard laboratory conditions make it a versatile reagent in synthetic chemistry. However, as with many sulfonyl chlorides, it is important to handle this compound with care due to its potential reactivity and the release of hydrochloric acid upon hydrolysis.
