Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key intermediate in the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical industries. The boronate ester group enables efficient carbon-carbon bond formation under mild conditions, allowing for the construction of biaryl and heterobiaryl systems. Its indoline scaffold is valuable in medicinal chemistry, often appearing in bioactive molecules and drug candidates. The tert-butyl carbamate (Boc) protecting group ensures stability during reactions and can be easily removed later in the synthesis sequence, making this reagent ideal for multi-step synthetic routes.
