Widely used in organic synthesis, this reagent serves as a powerful demethylating and dealkylating agent, particularly for cleaving methyl and alkyl ethers of phenols and carboxylic acids. It is effective in removing methyl groups from aromatic methyl ethers, enabling the selective production of phenolic compounds, which are valuable intermediates in pharmaceuticals, agrochemicals, and fine chemicals. Its high reactivity allows for efficient deprotection under mild conditions, making it preferred in complex molecule synthesis. Additionally, it is employed in the preparation of boron-containing compounds used in materials science and catalysis. Due to its moisture sensitivity, it is typically handled in anhydrous environments and used as a solution to improve handling and reactivity control.
