  • Applications

    (2R)-Tetrahydrofuran-2-carbaldehyde is a chiral aldehyde commonly used as a building block in organic synthesis to provide enantioenriched intermediates for pharmaceutical and agrochemical compounds; it is also employed as a precursor for fragrance materials in the fragrance industry and can be converted into diols or amino alcohols that serve as building blocks for asymmetric catalysts and specialty polymers; in cosmetics and personal care, it may play a role as a precursor for fragrance components or formulations with characteristic aromas; in the plastics and polymer sector, it can provide a chiral source for the synthesis of monomers or derivatives used in specialty polymers. Its use is subject to local regulations and formulation limits.
