Thial

Thial, also known as thiophene-2-carbaldehyde or 2-formylthiophene, is an organic compound with the chemical formula C5H4OS. It is a derivative of thiophene, a heterocyclic aromatic compound containing sulfur, with an aldehyde group attached at the second position. Thial is typically a colorless to pale yellow liquid with a distinct odor.

This compound finds applications as a building block in organic synthesis, particularly in the creation of pharmaceuticals, agrochemicals, and dyes. Its reactive aldehyde group can undergo various chemical transformations, allowing for the introduction of diverse functional groups into molecules. Thial is a valuable intermediate in the synthesis of more complex organic structures due to its participation in reactions such as condensation, oxidation, and reduction. It is also used in research laboratories for exploring new chemical reactions and developing novel materials.
