| | 4-Cyanotetrahydropyran Usage And Synthesis |
| Synthesis | 4-Cyanotetrahydropyran can be obtained by chlorination of phenol with chlorine gas to obtain 2,4,6-trichlorophenol, which is then condensed with p-nitrochlorobenzene. | | Chemical Properties | Yellow crystalline powder. Melting point 107°C, boiling point 210°C (0.8-0.93kPa), relative density 1.6424 (23/4°C). Vapor pressure 47Pa at 109°C. Freely soluble in benzene, toluene, slightly soluble in ether, insoluble in water (0.25ppm at 25°C). | | Uses | 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. |
