This compound is a substituted aryl triflate, primarily used as an electrophilic reagent in organic synthesis, particularly in cross-coupling reactions such as Suzuki, Heck, and Stille couplings. The trifluoromethanesulfonate (triflate) group acts as a highly reactive leaving group, facilitating the formation of carbon-carbon and carbon-heteroatom bonds for the synthesis of complex organic compounds. It is especially valuable as a building block in the preparation of pharmaceuticals, agrochemicals, and advanced materials. The 4-methoxy substituent provides electronic effects that influence reactivity, while the ortho-trimethylsilyl group enhances stability, directs regioselectivity, and enables further functionalizations, making it a preferred intermediate in demanding synthetic procedures.
