In organic chemistry, an oxime is an 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.

Oxime, any of a class of nitrogen-containing organic compounds usually prepared from hydroxylamine and an aldehyde, a ketone, or a quinone. Oximes have the structure X\Y/C= N―OH, in which X and Y are hydrogen atoms or organic groups derived by removal of a hydrogen atom from an organic compound.

An oxime is a functional group consisting of a hydroxyl group bonded to the nitrogen atom of an imine. An oxime derived from an aldehyde is called an aldoxime and derived from ketone is called ketoxime.

Oxime based cephalosporins have emerged as an important class of drugs with improved efficacy and a broad spectrum of anti-microbial activity against Gram-positive and Gram-negative pathogens. Among the several oxime based derivatives, cefuroxime, ceftizoxime, cefpodoxime and cefmenoxime are the FDA approved oxime-based antibiotics.

Two Oxime Varieties. Hydroxylamine combines with aldehydes 1 or ketones 2 to form aldoximes or ketoximes, respectively. These are two subclasses of oxime. For example, hydroxylamine combines with acetaldehyde… CH 3 –CHO + NH 2 –OH → CH 3 –C(H)=N–OH. And hydroxylamine combines with dimethylketone… (CH 3) 2 =O + NH 2 –OH → (CH 3 ...

The meaning of OXIME is any of various compounds containing the divalent group C=NOH and obtained chiefly by the action of hydroxylamine on aldehydes and ketones.

In manufacturing oil paints, oxime named Methyl ethyl ketone is used to prevent the skin from harsh chemical reactions. Structure of Oximes. As per Oxime structure, they are called nitrogen possessing organic compounds they are obtained from aldehyde, ketone, and hydroxylamine. Oximes are collected from aldehydes and are also called aldoximes.

Jan 12, 2022 · Nature Synthesis - Oximes are valuable motifs with diverse reactivity. This Review outlines the breadth of oxime reactivity including N–O bond fragmentation through transition metal catalysis...

Feb 28, 2022 · An oxime is a compound that has the following general structural formula. R 1 and R 2 could be hydrogen atoms, alkyl groups, aryl groups, or any combination thereof. eg: see also nitroso group

An oxime is one in a class of chemical compounds with the general formula R 1 R 2 C N O H, where R 1 is an organic side chain and R 2 is either hydrogen, forming an aldoxime, or another organic group, forming a ketoxime. Oximes can be formed by the action of hydroxylamine on aldehydes or ketones.
