For B2B buyers in the chemical industry, a thorough understanding of a compound's chemical profile – its properties, synthesis routes, and handling requirements – is fundamental to successful procurement and application. Diphenolic Acid (CAS 126-00-1), also known as 4,4-Bis(4-hydroxyphenyl)valeric acid, is a compound of significant industrial interest, and NINGBO INNO PHARMCHEM CO.,LTD. is pleased to provide a detailed look at its chemistry.

Diphenolic Acid possesses a molecular formula of C17H18O4 and a molar mass of 286.32 g/mol. Key physical properties include a melting point typically ranging from 167-170°C and a boiling point of approximately 388.69°C. Its appearance is generally described as a white to off-white solid. Solubility is notable in polar organic solvents like DMSO and methanol, though it is largely insoluble in non-polar solvents such as benzene and xylene. The compound's relatively high flash point (208°C) and its classification as a mild irritant (H315, H319, H335) are important considerations for handling and safety protocols, which we detail in our Material Safety Data Sheets (MSDS).

The primary synthesis route for Diphenolic Acid involves the acid-catalyzed condensation reaction between phenol and levulinic acid. This reaction yields Diphenolic Acid and water. The efficiency and purity of this process are critical for producing high-grade material. As a dedicated diphenolic acid manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. meticulously controls these synthesis parameters to ensure product quality. For R&D scientists, understanding these synthesis pathways can inform custom formulation efforts.
