Atomfair Phloretic acid C9H10O3 CAS 501-97-3

Description

Phloretic acid (CAS 501-97-3), also known as 3-(4-hydroxyphenyl)propanoic acid, is a phenolic derivative with the molecular formula C₉H₁₀O₃. This white to off-white crystalline powder is a valuable intermediate in organic synthesis and biochemical research, particularly in the study of polyphenols and their derivatives. With a molecular weight of 166.17 g/mol, it exhibits solubility in polar organic solvents such as ethanol, methanol, and DMSO, while being sparingly soluble in water. Phloretic acid is characterized by its aromatic phenol moiety and carboxylic acid functional group, making it a versatile building block for pharmaceuticals, polymer chemistry, and flavor/fragrance applications. Our high-purity grade (>98%) is rigorously tested by HPLC, NMR, and mass spectrometry to ensure consistency for sensitive research applications. Proper storage at 2-8°C in a tightly sealed container is recommended to maintain stability.
