1 4-DIOXANE ACS REAGENT >=99.0% CONTAINS <=25 PPM BHT AS STABILIZER (C005B-012519)

General description

1,4-Dioxane is a heterocyclic organic compound that is commonly used as a solvent in several chemical reactions. It is also used as a stabilizer in chlorinated solvents.

Application

1,4-Dioxane can be used as:      

• A solvent in the N-methylation of amines by reductive functionalization of CO₂ in the presence of NaBH₄ as the reducing reagent.      
• An additive to synthesize 3-hydroxylisoindolin-1-ones via hydroxylhydrative aza-cyclization of 2-alkynylbenzamide.

A mixture of 1,4-dioxane/ethanol/formic acid solvent system can be used in the depolymerization of lignin to synthesize value-added phenolic monomers.
