Used as a reagent in organic synthesis, particularly in cross-coupling reactions where the tetrahydro-2H-pyran-4-yl group acts as a protected form of a hydroxymethyl moiety. The trifluoroborate group enhances stability and solubility, making it suitable for Suzuki-Miyaura coupling under mild conditions. It enables the introduction of functionalized alkyl chains into aromatic or heteroaromatic systems, which is valuable in pharmaceutical and agrochemical synthesis. Its stability allows for storage and use in aqueous or mixed solvent systems without rapid decomposition.
