4-Methoxy-3-buten-2-one is an important precursor for the synthesis of 1-methoxy-3-trimethylsilyloxy-1,3-butadiene and the Danishefsky diene and its equivalent. It is widely used as a reactant in the synthesis of hydroisoquinoline derivatives. It is employed as an intermediate for the synthesis of manzamine. | [Toxics Screening Level]
Due to a lack of available toxicity information the ITSL is being set at the default value of 0.1 μg/m3 with annual averaging, based on R232(1)(i). |
