Dibutyl squarate Chemical Properties,Usage,Production

Chemical Properties

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.
