| | Propynol ethoxylate Usage And Synthesis |
| Description | Propargyl-PEG2-alcohol has propargyl and alcohol end groups. The propargyl can participate in copper-catalyzed Click Chemistry reactions with azides. | | Chemical Properties | Propynol ethoxylate(PME) is a clear colourless to pale yellow oil. | | Uses | Propynol Ethoxylate is an intermediate and it is shown to be used in the design and synthesis of a tag-free chemical probe for photoafiinity labeling. | | Application | Propynol ethoxylate is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. Propynol Ethoxylate is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups. | | General Description | Propynol ethoxylate, known as 2-propyn-1-ol, is a colourless flammable liquid with a pleasant odour. This volatile organic compound (VOC) occurs naturally in plants and animals and can also be synthesised in a laboratory environment. Propargyl alcohol polyoxyethylene ether has a wide range of applications and plays an important role in scientific research and industrial processes. It is used as a fuel, solvent and reagent in chemical reactions, as well as an important ingredient in the manufacture of many pharmaceuticals and industrial products. In scientific research, it is used as a reagent in organic synthesis, as a solvent in analytical chemistry and as a fuel in combustion studies. |
