Benzaldoxime Usage And Synthesis

Chemical Properties

White Solid

Uses

Oximes are used as a peel-preventing additive in paints and lacquers. It acts as an antioxidant against oxidative drying materials which forms sticky skin with air oxygen. Oximes are used as chemical building block for the synthesis of agrochemicals and pharmaceuticals. In medicine application, Oxime structure is effective in cholinesterase reactivators to treat the poisoning by organophosphates. Oxime is used as a ligand in transition-metal complex catalyst chemistry. Oxime acts as an antioxidant, radical scavenger which find applications in textile, plastic, paint, detergent, and rubber industry.

Uses

Benzaldoxime is an intermediate used to prepare Δ2-Isoxazoline derivatives as DNA methyltransferase 1 inhibitors. It is also used in the synthesis of potent 1,2,4-Oxadiazole EthR inhibitors.

Purification Methods

Crystallise the oxime from diethyl ether by adding pet ether (b 60-80o). The syn-isomer [622-32-2] has b 121-124o/12mm, m 34-36o. [Beilstein 7 H 218, 7 IV 527.]
