Diethyl squarate Chemical Properties,Usage,Production
Chemical Properties
clear yellow to light brownish liquid
Uses
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.
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.
General Description
The reaction of 3,4-diethoxy-3-cyclobutene-1,2-dione (squaric acid diethyl ester) with glycosylamines (formed by reducing oligosaccharides) was studied. The derivatives formed were linked to amino-functionalized lipids, solids or proteins.
