Summary

Boron Trichloride (BCl₃) is a colorless, toxic, and highly reactive gas with a pungent odor. As a strong Lewis acid, it plays a vital role in organic synthesis, semiconductor manufacturing, and high‑performance material production. It readily hydrolyzes in the presence of moisture, forming hydrogen chloride (HCl) and boric acid derivatives. BCl₃ is widely used in etching processes, catalyst production, and as a reagent in chemical vapor deposition (CVD).
