PRODUCT INTRODUCTION
description
Clofencet is a pyridazinone that is 1-(p-chlorophenyl)pyridazin-4-one which is substituted at positione 5 and 6 by carboxy and ethyl groups, respectively. It is used (particularly as the potassium salt, known as clofencet-potassium) as a chemical hybridisation agent for commercial hybrid seed production. It is not approved for use within the European Union. It has a role as a chemical hybridisation agent. It is a member of monochlorobenzenes, a monocarboxylic acid, a pyridazinone and a biaryl. It is a conjugate acid of a clofencet(1-).
