What is 4-Cyanotetrahydropyran?

The Uses of 4-Cyanotetrahydropyran

Herbicide.

Definition

ChEBI: Chlornitrofen is an aromatic ether, a member of chlorobenzenes and a C-nitro compound. It has a role as an EC 1.3.3.4 (protoporphyrinogen oxidase) inhibitor and a herbicide.

Safety Profile

Low toxicity by ingestion and skincontact. Mutation data reported. Used as an herbicide.When heated to decomposition it emits very toxic fumesof NOx and Clí.

Metabolic pathway

Degradation of chlornitrofen by microorganisms isolated from soils gives rise to the reduction of the nitro group of chlornitrofen to the amino analog, and the successive N-acetylation or N-methylation and the cleavage of the ether linkage are dominant metabolic pathways. The metabolic pathways, however, differ depending on microorganisms and the media. The replacement of the amino group by hydroxyl group, the reduction and successive formylation of p-nitrophenol, and the cleavage of the phenyl ring ultimately to produce CO2 are also observed.
