3-(2-Hydroxyphenyl)-1,3-diphenyl-1-propanone

Description:
3-(2-Hydroxyphenyl)-1,3-diphenyl-1-propanone, also known as benzoin, is an organic compound characterized by its structure, which includes a propanone moiety with two phenyl groups and a hydroxyl group attached to the aromatic ring. This compound typically appears as a white to pale yellow crystalline solid and is known for its role as a photoinitiator in polymerization processes, particularly in UV-curable coatings and inks. It exhibits good solubility in organic solvents such as ethanol and acetone, while being less soluble in water. The presence of the hydroxyl group contributes to its reactivity, allowing it to participate in various chemical reactions, including oxidation and condensation. Additionally, benzoin can undergo photochemical reactions when exposed to UV light, leading to the formation of free radicals, which are essential in initiating polymerization. Its applications extend beyond industrial uses, as it also has potential in organic synthesis and as a reagent in various chemical transformations. Safety considerations include handling it with care, as it may cause irritation upon contact with skin or eyes.
