Description

4-Biphenylaldehyde (CAS 3218-36-8 ), also known as 4-biphenylcarboxaldehyde, is an aromatic aldehyde used as a synthetic building block in specialty chemical manufacturing. Its biphenyl-aldehyde structure makes it a valued intermediate for constructing complex organic molecules across polymer, fragrance, and fine chemical applications. In polymer and materials chemistry, it serves as a monomer or crosslinking intermediate for engineering specialty resins and liquid crystal polymers where rigid aromatic backbones are required. Fragrance formulators incorporate it into fine fragrance and cosmetic compositions for its floral-aldehyde character, particularly in applications targeting premium personal care products. In pharmaceutical and agrochemical synthesis, it functions as a key intermediate for constructing biphenyl-containing active compounds for various industrial research purposes. Printing and packaging chemists also utilize it in the development of photoinitiator systems and UV-curable ink formulations to enhance performance in specialized coating applications. 4-Biphenylaldehyde is supplied as a white to off-white crystalline solid. It is commercially available at 99% purity, which is the standard specification for synthesis-grade procurement. Packaging is typically offered in gram to kilogram quantities, reflecting its primary positioning as a fine chemical intermediate rather than a bulk commodity for industrial use.
