Used as a silylating agent in organic synthesis, particularly for introducing hydrophobic groups into molecules. Commonly applied in the production of silicone-based polymers and resins, where it enhances thermal stability and water resistance. Also utilized as an intermediate in the synthesis of specialty silanes for surface modification of fillers and pigments in composite materials. Its reactivity with hydroxyl groups makes it effective for treating glass fibers and mineral surfaces to improve adhesion in reinforced plastics.
