This compound is a boron-containing heterocyclic building block widely used in pharmaceutical and agrochemical synthesis. The boronate ester group enables efficient Suzuki-Miyaura cross-coupling reactions, making it a key intermediate for constructing complex pyridine-based molecules. It is extensively utilized in the synthesis of kinase inhibitors, GPCR ligands, and other drug candidates targeting various diseases. The benzyloxy group serves as a protecting group for the hydroxyl moiety, which can be selectively removed under mild conditions. In addition, it is employed in academic research for library synthesis and structure-activity relationship (SAR) studies. Its high purity and stability make it a preferred choice for both industrial and laboratory-scale synthesis.
Acute toxicity data is limited; however, it is considered to have low acute toxicity. Skin contact may cause redness, itching, and dermatitis; rinse with plenty of water immediately. Eye contact can lead to severe irritation, tearing, and conjunctivitis; flush with clean water for at least 15 minutes and seek medical attention if irritation persists. Inhalation of dust may irritate the respiratory tract, causing cough and sore throat. Use in a well-ventilated area; wear nitrile gloves, safety goggles, and a dust mask during handling. Store separately from food, feed, and oxidants. Dispose of waste according to local hazardous waste regulations.
