Product Description:

2,2-Diphenylacetaldehyde is an organic compound featuring a diphenylmethyl group directly attached to an aldehyde functional group. Its molecular formula is C14H12O, and it is typically a colorless to pale yellow liquid or low-melting solid. The compound is characterized by its sterically hindered aldehyde moiety, which imparts unique reactivity in organic synthesis. As a versatile synthetic building block, 2,2-Diphenylacetaldehyde is primarily utilized in the construction of complex organic molecules. It serves as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of small-molecule drug candidates targeting neurological and cardiovascular pathways. Its aldehyde group readily participates in condensation reactions, reductive amination, and Grignard additions, making it valuable for creating carbon-carbon bonds and introducing the diphenylmethyl pharmacophore. In addition to its role in medicinal chemistry, this compound is employed in the preparation of fine chemicals, agrochemicals, and specialty materials. It is also used as a starting material for synthesizing diphenylacetic acid derivatives and other functionalized compounds. Due to its reactivity, it should be stored under inert atmosphere and handled with appropriate safety precautions to avoid oxidation and polymerization.
