Products Description of 1,3-Dioxan-2-one CAS#2453-03-4
1,3-Dioxan-2-one (TMC) is a cyclic carbonate compound with the molecular formula C₄H₆O₃ and CAS number 2453-03-4. It is mainly used as a monomer in the synthesis of poly(trimethylene carbonate) (PTMC), a biodegradable polymer. This compound typically appears as white to off-white crystals and has a melting point of 45–47°C. It is readily soluble in organic solvents, including methanol. For proper storage and stability, it should be kept at a low temperature of 2–8°C under an inert gas atmosphere.

Primary Applications
Ring-Opening Polymerization: 1,3-Dioxan-2-one is used in bulk ring-opening polymerization initiated by butyltin chlorides (BuSnCl, Bu₂SnCl, or Bu₃SnCl) to produce poly(trimethylene carbonate) (PTMC).
Copolymerization and Material Modification: It can be copolymerized with monomers such as ε-caprolactone or L-lactide to adjust the mechanical properties, degradation rate, and thermodynamic behavior of the resulting materials, making it promising for biomedical applications.
Homopolymer and Crosslinked Material Applications: PTMC can also be copolymerized with other lactone monomers. Following crosslinking, it can form a flexible, elastic network with properties similar to those of polydimethylsiloxane (PDMS) rubber.
