clear colorless to yellow liquid | [Uses]
3,4-Dibutoxy-3-cyclobutene-1,2-dione was used in the synthesis of novel semisquarylium dye, useful for highly selective Hg2+ sensing in aqueous media. It was also employed in the synthesis of 3-butoxy-4-(1,3,3-trimethyl-2,3-dihydro-1H-2-indolylidenemethyl)-3-cyclobutene-1,2-dione, intermediate for the synthesis of squaryl dyes. | [Uses]
Squaric acid and its derivatives (Dibutyl squarate) are used in synthesis of pharmaceutical intermediates, squarylium dyes, and photoconducting squaraines.
| [Definition]
ChEBI: A cyclic ketone and diether that is a dibutyl ether derivative of squaric acid. | [General Description]
3,4-Dibutoxy-3-cyclobutene-1,2-dione is the dialkyl ester of squaric acid. |
