Glycidol (2,3-epoxy-1-propanol) is a versatile epoxide intermediate used in organic synthesis, pharmaceuticals, and polymer chemistry as a key building block for resins, surfactants, and fine chemicals. Its main use is as a stabilizer for vinyl polymers, and it also serves as an intermediate for glycerol and glycidyl ethers and as a diluent for epoxy resins. It serves as a precursor for glycidol derivatives and is critical in creating specialty chemicals with tailored properties. This chemical has a CAS number of 556-52-5, a molecular formula of (CH2CHO)CH2OH, and a molecular weight of 74.08 g/mol. It must be stored between 2 to 8°C and carries a "Danger" signal word due to its hazardous nature. Molekula supplies Glycidol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
