Product Description:

Thiophene-3-carboxaldehyde is an organic compound featuring a thiophene ring substituted with a formyl group at the 3-position. It is a colorless to pale yellow liquid with a molecular formula of C5H4OS and a molecular weight of 112.15 g/mol. This compound is a versatile building block in organic synthesis, particularly valued for its aldehyde functionality which readily undergoes condensation and other reactions. Its primary industrial significance lies in the field of materials chemistry, where it serves as a crucial precursor for the synthesis of various organic electronic materials. It is extensively used in the development of organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and other organic semiconductor devices. The thiophene moiety contributes to good charge transport properties, while the aldehyde group allows for the construction of conjugated systems, dyes, and complex heterocyclic structures essential for optoelectronic applications. As a fundamental synthetic intermediate, it is also employed in pharmaceutical and agrochemical research for constructing thiophene-containing bioactive molecules. It should be handled with care as it is an irritant to the skin, eyes, and respiratory system.
