Propargyl alcohol is an organic compound with a terminal alkyne functional group and a hydroxyl group, widely used as a solvent, intermediate in organic synthesis, and in the production of pharmaceuticals, agrochemicals, and specialty polymers. It is also employed in the manufacture of propargyl derivatives and as a cross-linking agent in resins. It also serves as a corrosion inhibitor protecting steel from hydrochloric acid, including in oil drilling, and as a stabilizer in chlorinated hydrocarbon solvent formulations. This chemical has a CAS number of 107-19-7, a molecular formula of HC≡CCH₂OH, and a molecular weight of 56.06 g/mol. It must be stored between 2 to 8°C and is classified with the signal word "Danger" due to its hazardous properties. Molekula supplies propargyl alcohol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
