Applicazioni

Thiophene-3-carboxaldehyde has been used in the synthesis of series of 4-substituted 2-thiophenesulfonamides, acetal and ketal derivatives of 4?-demethylepipodophyllotoxin-β-D-glucoside and epipodophyllotoxin-β-D-glucoside. Also has been used to produce 1,2-di-3-thienyl-2-hydroxyethanone (3,3?-thenoin), 3-thienyl symmetric analog of benzoin.

Note

It is sensitive to air. Incompatible with oxidizing agents and heat.
