Description and Uses

2-Thiophenecarboxaldehyde, also known as alpha-formylthiophene or 2-thienylaldehyde, belongs to the class of organic compounds known as aryl-aldehydes. Aryl-aldehydes are compounds containing an aldehyde group directly attached to an aromatic ring. 2-Thiophenecarboxaldehyde is a sulfurous tasting compound. 2-Thiophenecarboxaldehyde has been detected, but not quantified in, asparagus (Asparagus officinalis). This could make 2-thiophenecarboxaldehyde a potential biomarker for the consumption of these foods. 2-Thiophenecarboxaldehyde is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites.

2-Thiophenecarboxaldehyde is used in the synthesis of β-aryl-β-amino acids, urea derivatives. Arylation reagent. Also used to synthesize unsaturated ketones as antiviral and cytotoxic agents.
