| | PENTANOCHLOR Usage And Synthesis |
| Chemical Properties | Solid. Insoluble in water; sol-
uble in pine oil, diisobutyl ketone, isophorone, and
xylene. Combustible. | | Uses | Pentanochlor can be used in agricultural use and biological study of herbicide composition containing a pyrazolyl pyrazole derivative. | | Uses | Herbicide. | | Production Methods | The production of pentanochlor typically involves the acylation of a substituted aniline, specifically 3-chloro-4-methylaniline, with 2-methylpentanoic acid or its activated derivative such as an acid chloride. This reaction forms the amide bond central to pentanochlor’s structure, yielding N-(3-chloro-4-methylphenyl)-2-methylpentanamide. The process is carried out under controlled conditions using an organic solvent and a base to neutralise the byproduct (usually HCl if an acid chloride is used). After the reaction, the crude product is purified through recrystallisation or chromatography to achieve the desired purity for agricultural use. | | Definition | ChEBI: Pentanochlor is an anilide. | | Mechanism of action | Selective with contact action. Photosynthetic electron transport inhibitor at the photosystem II. | | Enzyme inhibitor | This photosynthetic electron transport inhibitor (FW = 239.74 g/mol; CAS 2307-68-8), also known as Solan, (RS)-3’-chloro-2-methylvaler-ptoluidide, and N-(3-chloro-4-methylphenyl)-2-methylpentanamide, is a selective pre- and post-emergence herbicide used to control annual weeds in fields producing carrots, celery, fennel, and parsley. Pentanochlor is also used in contact sprays with flowers and ornamental plants | | Pesticide Type | Herbicide |
