2,5-Thiophenedicarboxaldehyde Usage And Synthesis

Chemical Properties

PALE BROWN-ORANGE TO PALE BROWN POWDER

Uses

2,5-Thiophenedicarboxaldehyde acts as a reagent in the synthesis of N,N''-bis-(mercaptophenylimine)thiophenedicarboxaldehyde Schiff base, and also functions as an intermediate in many organic synthesis.

Uses

2,5-Thiophenedicarboxaldehyde may be employed in the following studies:

• Asymmetric synthesis of bis-homoallylic alcohols.
• Synthesis of new symmetrical arylene bisimide derivatives.
• As dialdehyde monomer in the synthesis of silicon-containing poly(p-phenylenevinylene)-related copolymers having uniform p-conjugated segment regulated by organosilicon units.
• Synthesis of 2,5-bis[2-(5-N-isopropylamidino)benzimidazoyl]thiophene hydrochloride.
