CAS 652-39-1

3-Fluorophthalic anhydride

Description:

3-Fluorophthalic anhydride, with the CAS number 652-39-1, is a chemical compound that belongs to the class of phthalic anhydrides, which are cyclic anhydrides derived from phthalic acid. This substance is characterized by the presence of a fluorine atom at the 3-position of the phthalic structure, which influences its reactivity and properties. It typically appears as a white to light yellow crystalline solid and is known for its high melting point and low solubility in water, but it is soluble in organic solvents. 3-Fluorophthalic anhydride is primarily used in the synthesis of various fluorinated compounds and as an intermediate in the production of specialty chemicals, including polymers and resins. Its reactivity is attributed to the anhydride functional group, which can undergo hydrolysis to form corresponding acids or react with nucleophiles. Safety precautions are necessary when handling this compound, as it can be irritating to the skin, eyes, and respiratory system.
