The GHS information provided by 1 company from 1 notification to the ECHA C&L Inventory.
使用4H-Pyran-4-one was used in the synthesis of probes grafted on the lipid headgroups.
製造方法1) from Diethylacetone dioxalate by cyclization to Chelidonic acid (gamma-Pyrone- 2,6-dicarboxylic acid). The acid yields 4H-Pyran-4-one by decarboxylation.2) by heating of I-Methoxypent-l -en-3-yn-5- al diethylacetal with Methanol and water, using Mercuric sulfate or Sulfuric acid catalyst.
純化方法Purify -pyrone by vacuum distillation; the distillate crystallises and is hygroscopic. It is non-steam vola
定義ChEBI: A pyranone that is 4H-pyran substituted by an oxo group at position 4.
