CAS 77-09-8: 3,3-Bis(4-hydroxyphenyl)phthalide

Description: 3,3-Bis(4-hydroxyphenyl)phthalide, also known as bisphenol A phthalide, is an organic compound characterized by its structure, which includes two hydroxyphenyl groups attached to a phthalide moiety. This compound is typically a white to off-white crystalline solid at room temperature. It exhibits good thermal stability and is soluble in organic solvents such as ethanol and acetone, but has limited solubility in water. The presence of hydroxyl groups contributes to its potential as a building block in polymer chemistry, particularly in the synthesis of polycarbonate and epoxy resins. Additionally, it may exhibit antioxidant properties, making it of interest in various applications, including plastics and coatings. However, like many phenolic compounds, it may also raise concerns regarding endocrine disruption, necessitating careful handling and assessment of its environmental impact. Overall, 3,3-Bis(4-hydroxyphenyl)phthalide is a versatile compound with significant implications in materials science and industrial applications.
