Used as a deuterated silane coupling agent in specialized synthesis where isotopic labeling is required. Facilitates surface modification of materials in analytical research, particularly in NMR studies to track reaction pathways or study molecular interactions. Employed in the development of deuterated polymers and siloxane-based networks for enhanced stability and performance in extreme environments. Also serves as a reducing agent in selective deuteration reactions, enabling incorporation of deuterium into target molecules for pharmaceutical and mechanistic studies.
