Used primarily as an intermediate in organic synthesis, this compound serves in the preparation of pharmaceuticals and fine chemicals. Its alkyne functionality allows for use in coupling reactions, such as Sonogashira or Cadiot-Chodkiewicz, enabling the construction of complex molecular structures. It is also employed in the development of specialty materials and research compounds where phenyl-substituted alkynes are required. Due to its reactivity, it finds niche applications in laboratory settings for synthesizing ketones, enynes, and other functionalized derivatives.
