white to light yellow crystal powder | [Uses]
2-Thiopheneacetic acid is used in the preparation of rosette-like nanoscale gold materials. Further, it is used as a pharmaceutical intermediate for cefaloridine and cefalotin sodium. | [Definition]
ChEBI: 2-thienylacetic acid is a thiophene compound having a carboxymethyl group at the 2-position. It has a role as an allergen. It is a member of thiophenes and a monocarboxylic acid. It is functionally related to an acetic acid. It is a conjugate acid of a thien-2-ylacetate. | [Synthesis Reference(s)]
Canadian Journal of Chemistry, 46, p. 1057, 1968 DOI: 10.1139/v68-179 Journal of the American Chemical Society, 72, p. 4326, 1950 | [General Description]
Adsorption of 2-thiopheneacetic acid on XAD-4, NDA-100 and ND-90 resin has been investigated. A new polymeric complex of Cu(II) and 2-thiopheneacetic acid has been synthesized and characterized by IR and Raman spectroscopy. | [Purification Methods]
Crystallise the acid from ligroin, hexane and/or distil it in a vacuum. The amide has m 148o (from H2O or pet ether). [Beilstein 18 H 293, 18 III/IV 4062, 18/6 V 207.] |
