CAS 2351-37-3: 4,4′-Biphenyldicarbonyl chloride

Description: 4,4′-Biphenyldicarbonyl chloride, with the CAS number 2351-37-3, is an organic compound characterized by the presence of two carbonyl chloride (acyl chloride) functional groups attached to a biphenyl structure. This compound typically appears as a white to light yellow crystalline solid and is known for its reactivity, particularly in acylation reactions. It is soluble in organic solvents such as dichloromethane and chloroform but is generally insoluble in water due to its hydrophobic biphenyl backbone. The presence of the carbonyl chloride groups makes it a useful intermediate in organic synthesis, particularly for the preparation of various derivatives, including amides and esters. However, it is important to handle this compound with care, as it can be corrosive and may release toxic gases upon hydrolysis. Proper safety precautions, including the use of personal protective equipment and working in a well-ventilated area or fume hood, are essential when working with this chemical.
