WebOxime. In organic chemistry, an oxime is a organic compound belonging to the imines, with the general formula RR’C=N−OH, where R is an organic side-chain and R' may be hydrogen, forming an aldoxime, or another organic group, forming a ketoxime. O-substituted oximes form a closely related family of compounds.

WebOximes are the chemical composites that belong to the class of imines, having the general formula of R1R2C = N OH. Oximes can also be made by the action of hydrogen-giving reagents upon certain nitro composites or by the isomerization of nitroso composites.
