  • Applications

    2-Octanone, oxime (CAS 7207-49-0) is primarily used as an intermediate in industrial organic synthesis, including as a Beckmann rearrangement precursor to amides and as a building block for oxime ethers and related nitrogen-containing heterocycles; it also serves as a pharmaceutical synthesis intermediate for certain drug precursors. In perfumery and cosmetics, it can be used as a fragrance intermediate or odorant component. In polymers and coatings, it provides a starting material for specialty monomers and can be employed in resin formulations or crosslinking chemistry. Its use is governed by local regulations and formulation limits.
