Description

2-(2-Thienyl)Propionic Acid CAS NO 54955-39-4 is a high-purity organic compound featuring a thiophene ring, a versatile heterocyclic building block, attached to a propionic acid chain. This structure makes it a valuable intermediate for synthesizing more complex molecules in advanced research and industrial manufacturing. It is primarily sought after by pharmaceutical R&D teams and fine chemical producers for developing active pharmaceutical ingredients (APIs) and specialty chemicals.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel drug candidates, particularly those targeting the central nervous system or possessing anti-inflammatory properties.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and plant growth regulators that incorporate the thiophene moiety.
• Material Science Research: Serves as a precursor for monomers or functional additives in the development of conductive polymers and advanced organic electronic materials.
• Ligand and Catalyst Development: Employed in organic chemistry research to create novel ligands for metal catalysts used in cross-coupling and other catalytic reactions.
• Fine Chemical Production: An essential intermediate for manufacturing dyes, pigments, and other specialty performance chemicals.
