2,3-Dimethyl-2,3-diphenylbutane (CAS: 1889-67-4) is a symmetric diarylalkane featuring two quaternary carbon centers. It is primarily used as a β-nucleating agent for polypropylene, improving transparency, heat deflection temperature, and impact strength. It also serves as a sterically hindered building block in organic synthesis.
