4,4'-Biphenyldicarbaldehyde(CAS: 66-98-8)

4,4'-Biphenyldicarbaldehyde (CAS: 66-98-8) is a white crystalline solid with a molecular weight of approximately 204.17 g/mol. It has a low solubility in water but is soluble in organic solvents like ethanol and acetone. Chemically, it is highly reactive, particularly towards nucleophiles, making it useful in various organic synthesis reactions.

4,4'-Biphenyldicarbaldehyde is typically synthesized by the oxidation of 4,4'-biphenyldiyl diacetate using a suitable oxidizing agent like potassium permanganate or potassium dichromate under acidic conditions. This process provides a high yield and good selectivity for the desired product.

4,4'-Biphenyldicarbaldehyde finds applications in the pharmaceutical, polymer, and semiconductor industries. It serves as a key intermediate in the synthesis of various organic compounds and is also used in the development of sensors and conductive polymers.

When handling 4,4'-Biphenyldicarbaldehyde (CAS: 66-98-8), it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and lab coats. Work should be conducted in a well-ventilated area or fume hood to minimize inhalation risks. Spills should be handled with caution and cleaned up using appropriate materials. Always refer to the Safety Data Sheet (SDS) for detailed safety guidelines.
