Aplicaciones

Reagent used in synthesis of fused 3-methylfuransDimedone is used in organic chemistry to identify the presence of aldehyde group. It is also used as a catalyst in the formation of transition-metal complexes. Further, it is also employed in colorimetry, crystallography, luminescence and spectrophotometric analysis. In addition to this, it is used in the synthesis of naturally occurring fused 3-methylfurans.

Notas

Light sensitive. Incompatible with oxidizing agents, strong acids and strong bases.
