LiHMDS is often used in organic chemistry as a strong non-nucleophilic base. Its conjugate acid has a pKa of ~26, making it is less basic than other lithium bases, such as LDA (pKa of conjugate acid ~36), but it is more sterically hindered and hence less nucleophilic. It can be used to form various organolithium compounds, including acetylides or lithium enolates.
