4,4′-Difluorobenzophenone

Description:

4,4′-Difluorobenzophenone, with the CAS number 345-92-6, is an organic compound characterized by its structure, which consists of two benzene rings connected by a carbonyl group (C=O) and substituted with two fluorine atoms at the para positions of one of the benzene rings. This compound is typically a white to light yellow crystalline solid and is known for its role as a photoinitiator in polymerization processes and as an intermediate in organic synthesis. It exhibits moderate solubility in organic solvents such as ethanol and acetone, while being less soluble in water. The presence of fluorine atoms enhances its chemical stability and alters its electronic properties, making it useful in various applications, including UV-absorbing materials and pharmaceuticals. Additionally, 4,4′-Difluorobenzophenone may exhibit specific absorption characteristics in the UV-visible spectrum, which can be leveraged in analytical chemistry for detection and quantification purposes. Safety precautions should be observed when handling this compound, as it may pose health risks upon exposure.
