For professionals in the chemical industry, a deep understanding of the properties and reliable synthesis routes of key intermediates like 4,4'-Biphenol (CAS 92-88-6) is crucial for informed purchasing decisions and effective application development. This compound, also known by various synonyms such as p,p'-Biphenol or 4,4'-Dihydroxybiphenyl, offers a unique combination of thermal stability and reactivity that makes it highly valuable.

Chemically, 4,4'-Biphenol is a white crystalline powder with a relatively high melting point, typically around 280-282°C, which underscores its thermal resilience. Its molecular formula is C12H10O2, and it possesses two hydroxyl groups attached to a biphenyl core. This structure is key to its functionality, enabling it to participate in polymerization reactions and act as a precursor for advanced materials. Its solubility in water is limited, but it is more soluble in organic solvents, which is a consideration for various processing and formulation techniques.

From a synthesis perspective, 4,4'-Biphenol can be produced through several industrial routes. Common methods include the alkaline fusion of 4,4'-biphenyldisulfonic acid or oxidative coupling of phenol derivatives. Another significant method involves the debutylation of tert-butylated biphenols. The choice of synthesis method can influence the purity and the presence of isomeric byproducts, making it important for buyers to specify purity requirements, such as the common 98% or 99% assay, depending on the intended application. For instance, the synthesis of high-performance polymers often demands higher purity grades to ensure consistent polymerization and final product properties.

Beyond its role in polymers, 4,4'-Biphenol's antioxidant capabilities are well-documented. It serves as an effective stabilizer for petroleum products and as an intermediate in the dye industry. These diverse applications highlight its importance as a versatile chemical commodity.
