| Hazard Information | Back Directory | [Uses]
Miticide. | [Description]
Dinobuton is a dinitrophenol multi-use pesticide which is not approved for use in the UK nor the EU. It has a low aqueous solubility but soluble in most organic solvents. Limited information is available regarding its environmental fate but is reported as being non-mobile. It is moderately toxic to mammals, birds and bees but considered highly toxic to fish. Limited data is available on its toxicity to humans but some reports suggest it is a possible cardiovascular, liver and kidney toxicant | [Definition]
ChEBI:Dinobuton is a C-nitro compound. | [Production Methods]
The commercial production of dinobuton involves synthesising a dinitrophenol-based compound through a series of organic reactions that introduce key functional groups responsible for its fungicidal and acaricidal activity. The process typically starts with the preparation of a sec-butyl-substituted aromatic intermediate, which is then nitrated to form the dinitrophenol core. This is followed by carbonate esterification, linking the dinitrophenol moiety to the sec-butyl group via a carbonate bridge. | [Mechanism of action]
Non-systemic, rapid contact action. Uncoupler of oxidative phosphorylation via disruption of proton gradient. | [Metabolic pathway]
Dinobuton is metabolised in plants and animals via common metabolic
pathways. The primary reaction is hydrolytic cleavage of the
carbonate-dinitrophenyl linkage to yield dinoseb. Further reduction of
the nitro-groups of dinoseb yields the corresponding monoamino and
diamino analogues. Acetylation and deamination via hydroxylation/
elimination, and oxidation of the sec-butyl moiety also occurred. N- and
O-Conjugation as glucosides and glucuronides occurred in both plants
and animals. The metabolic pathways of dinobuton are presented in
Scheme 1. | [Degradation]
There is limited information on the hydrolytic stability of dinobuton (1).
Marchenko and Vakulenko (1983) reported that the hydrolysis DT50 values
of dinobuton in pH 2, 7 and 11 buffer solutions at 22 °C were 15 days,
17 days and 4 hours, respectively. In vitro studies showed the rapid
hydrolysis of dinobuton to dinoseb [ 2-sec-butyl-4,6-dinitrophenol (2)] by
tissue homogenates of spider mites and animal tissues. Once generated,
dinoseb was stable to hydrolytic and photolytic degradation under acidic
condition but was readily degraded under alkaline conditions (Brestkin
et al., 1978; Molnar, 1935). Uncharacterised complex polar materials
were reported as photodecomposition products of dinoseb (Matsuo and
Casida, 1970). Grechko et al. (1986) reported that the DTW for dinobuton
in aqueous solution under UV light irradiation (365 nm) was <30 min. | [Pesticide Type]
