General description

2-Chlorobenzamide is the major degradation product of CCU (1-(2-chlorobenzoyl)-3-(4-chlorophenyl) urea), a new insect growth regulator. It undergoes room temperature Pd-mediated hydrodehalogenations with KF and polymethylhydrosiloxane (PMHS) to yield benzamide. t undergoes reduction with NaBH4 in diglyme at 162°C to yield 2-chlorobenzonitrile.

1-(2-chlorobenzoyl)-3-(4-chlorophenyl)urea (CCU), a new analogue of diflubenuron and PH-6038, has been widely used in agriculture and forestry as a molt-inhibiting hormone insecticide which was developed in China. 2-Chlorobenzamide, a main degradation product of CCU in the environment, has been identified

It has been reported that 1-(2-chlorobenzoyl)-3-(4-chlorophenyl) urea (CCU), an insect growth regulator, has no measurable toxicity to nontarget organisms and is essentially harmless to humans. However, one of its degradation products, 2-chlorobenzamide (CBA), is suspected of being a carcinogen. Therefore

It is reported that 2-chlorobenzamide, one of the chief degradation products of CCU (1-(2-chlorobenzoyl)-3-(4-chlorophenyl) urea), a new insect growth regulator, is a potential carcinogen, but few studies about its environmental stability have been found. This paper is concerned with the
