4,4-Bis(4-hydroxyphenyl)pentanoic acid(CAS: 126-00-1)

4,4-Bis(4-hydroxyphenyl)pentanoic acid (CAS: 126-00-1) is a white crystalline solid with a molecular weight of approximately 298.28 g/mol. It is poorly soluble in water but soluble in organic solvents such as ethanol and acetone. Chemically, it is relatively stable under normal conditions, but it can undergo hydrolysis under acidic or basic conditions. It is not reactive towards common organic reagents but can participate in condensation reactions under certain conditions.

4,4-Bis(4-hydroxyphenyl)pentanoic acid can be synthesized through a condensation reaction of 4-hydroxybenzoic acid with pentanedioic acid. The reaction is typically catalyzed by a Lewis acid like aluminum chloride or zinc chloride. The yield is around 85-90%, and the product is purified by recrystallization from ethanol. The reaction is conducted under mild conditions to ensure high selectivity and purity.

4,4-Bis(4-hydroxyphenyl)pentanoic acid (CAS: 126-00-1) is primarily used in the pharmaceutical and polymer industries. It serves as a precursor for the synthesis of various drug molecules and can be used to improve the properties of certain polymers, such as increasing their mechanical strength and thermal stability. Additionally, it has potential applications in the development of sensors and semiconductors.

When handling 4,4-Bis(4-hydroxyphenyl)pentanoic acid (CAS: 126-00-1), it is important to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. Work should be performed in a well-ventilated area or a fume hood to minimize exposure. Spills should be cleaned up immediately with appropriate absorbent materials. Always refer to the Safety Data Sheet (SDS) for specific handling and disposal instructions, and ensure that the substance is stored in a cool, dry place away from direct sunlight and heat sources.
