1,3-Bis(4,5-dihydro-2-oxazolyl)benzene CAS 34052-90-9 is a white to light yellow crystalline powder with high melting point, soluble in some organic solvents, and relatively stable chemical properties. Under certain conditions, oxazoline rings can be opened to react, and benzene rings can be substituted. Therefore, dioxazoline can often be used as chain extender or crosslinking agent in polymers.
