| | 2-Amino-3-chloro-1,4-naphthoquinone Usage And Synthesis |
| Chemical Properties | Orange powder | | Uses | 2-Amino-3-chloro-1,4-naphthoquinone is a pesticide residue in crops. | | Definition | ChEBI: Quinoclamin is a member of 1,4-naphthoquinones. | | Production Methods | Quinoclamine is commercially produced via a nucleophilic substitution reaction of 2,3-dichloro-1,4-naphthoquinone (derived from chlorination of 1,4-naphthoquinone) with ammonia or ammonium salts in refluxing ethanol or aqueous media under controlled pH and temperature to selectively displace the 2-chloro group, yielding the 2-amino-3-chloro-1,4-naphthoquinone core. The technical-grade active ingredient is purified by recrystallisation from organic solvents like dichloromethane or ethyl acetate. | | Mechanism of action | Selective. Quinoclamine works by inhibiting photosynthesis. It achieves this by binding to the Qв binding site on the D1 protein of the Photosystem II (PSII) reaction centre, which is part of the electron transport chain. This leads to disruption of carbon dioxide fixation and the production of nutrients required for plant survival, causing rapid cellular damage, which manifests as chlorosis and necrosis. | | Pesticide Type | Herbicide; Algicide |
