| | 3,5-Dichloro-2-pyridone Usage And Synthesis |
| Chemical Properties | white to light beige crystalline powder | | Uses | 3,5-dichloro-2-pyridoxyacetic acid derived from 3,5-dichloro-2-pyridone serves as a direct pyridine analog of the herbicide 2,4-dichlorophenoxyacetic acid[1]. 3,5-dichloro-2-pyridone is used as a reactant in the Mitsunobu reaction with ethyl lactate, diisopropyl azodicarboxylate, and triphenylphosphine in N,N-dimethylformamide at room temperature to produce both N-alkylated and O-alkylated products[2]. | | Definition | ChEBI: 3,5-Dichloro-1,2-dihydropyridin-2-one is a chloropyridine. | | References | [1]
