Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
La 3,4-dibutoxy-3-cyclobutène-1,2-dione a été utilisée dans la synthèse de nouveaux colorants semisquarylium, utiles pour la détection hautement sélective du Hg2+ dans des milieux aqueux. Il a également été utilisé dans la synthèse de la 3-butoxy-4-(1,3,3-triméthyl-2,3-dihydro-1H-2-indolylidèneméthyl)-3-cyclobutène-1,2-dione, un intermédiaire pour la synthèse de colorants squaryles.

Solubilité
Insoluble dans l’eau.
