Glycolaldehyde dimer, 95%

About Glycolaldehyde dimer, 95%

Glycolaldehyde dimer is an alcohol building block carrying the CAS registry number 23147-58-2 with a typical assay of 95%. The compound has the formula C4H8O4, corresponding to a molecular weight of 120.1 g/mol. Systematically, it is named 1,4-dioxane-2,5-diol. It is also known as Hydroxyacetaldehyde dimer or 2,5-Dihydroxy-1,4-dioxane.

It is supplied as a white powder. Literature values give a boiling point of 312.4 °C. Recommended storage is at 2–8 °C, with the container kept tightly sealed. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for organic synthesis, catalysis and enzyme inhibition studies. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 1 g, 5 g, 25 g and 100 g, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
