Terephthalaldehyde CAS 623-27-8

Terephthalaldehyde is a white to light yellow crystalline powder with characteristic aroma.Mainly used as organic synthesis intermediates (such as fluorescent whitening agent, polyester resin), pharmaceutical raw materials and monomers of functional materials, its high reactivity and symmetrical structure are conducive to polymerisation.It needs to be sealed and stored away from light, and is irritating to eyes and respiratory tract.
