1H-pyrazole-4-sulfonyl chloride

Description:

1H-Pyrazole-4-sulfonyl chloride, with the CAS number 288148-34-5, is a chemical compound characterized by the presence of a pyrazole ring substituted with a sulfonyl chloride group at the 4-position. This compound typically appears as a white to off-white solid and is known for its reactivity due to the sulfonyl chloride functional group, which can participate in nucleophilic substitution reactions. It is soluble in polar organic solvents, making it useful in various synthetic applications. The sulfonyl chloride moiety is a versatile electrophile, allowing for the introduction of various nucleophiles, which can lead to the formation of sulfonamides or other derivatives. 1H-Pyrazole-4-sulfonyl chloride is often utilized in medicinal chemistry and material science for the development of pharmaceuticals and agrochemicals. Safety precautions should be taken when handling this compound, as sulfonyl chlorides can be corrosive and may release toxic gases upon reaction with water or moisture.
