Uses
Diethyl squarate is an intermediate for pharma products, for photochemicals used in the dry-view process, in synthesis of photosensitive squaraine dyes (eg. laser dyes used in CD-Rom) and as intermediate for functional polymers. 3,4-Dethoxy-3-cyclobutene-1,2-dione is used as a starting material for synthesis of furanones and quinones. It undergoes ethoxy substitution with amines and unsaturated organosilanes.
