  • Applications

    Chemical name: Benzaldehyde Oxime; CAS 932-90-1. In real-world use, benzaldehyde oxime is primarily employed as an organic synthesis intermediate to prepare oxime derivatives and other functional compounds, supporting the manufacture of pharmaceutical precursors and dye/pigment-related products; it is also evaluated as a precursor in fragrance research and flavor science, and may serve as a building block for coatings, polymers, and industrial formulations; its use is subject to local regulations and formulation limits.
