Triphenylarsine oxide (Cat No.:M049791) is an organoarsenic compound consisting of a central arsenic atom bonded to three phenyl groups and one oxygen atom via a double bond. It is a white to off-white crystalline solid, typically used as an intermediate in organic synthesis and coordination chemistry. The molecule’s lone pair on arsenic makes it a potential ligand in transition metal complexes, offering applications in catalysis and material science. Its structural similarity to phosphine oxides aids in studying structure–reactivity relationships.
