CAS 652-40-4

3,6-difluorophthalic anhydride

Description:

3,6-Difluorophthalic anhydride, with the CAS number 652-40-4, is an organic compound characterized by its anhydride functional group derived from phthalic acid. It features two fluorine atoms substituted at the 3 and 6 positions of the phthalic structure, which significantly influences its chemical reactivity and properties. This compound typically appears as a white to light yellow crystalline solid and is known for its high melting point. It is soluble in organic solvents such as acetone and chloroform but has limited solubility in water. The presence of fluorine atoms enhances its thermal stability and can impart unique electronic properties, making it useful in various applications, including the synthesis of polymers and as an intermediate in organic synthesis. Additionally, 3,6-difluorophthalic anhydride can be reactive towards nucleophiles, making it valuable in the production of fluorinated compounds. Safety precautions should be observed when handling this substance, as it may cause irritation to the skin and eyes.
