General Manufacturing Information2-Thiophenecarboxaldehyde: ACTIVE
Applications · 4 items

Description2-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.

UsesThiophene derivatives, introducing thenyl group into organic compounds.

Uses2-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.

General DescriptionPharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards
