3-Thienylmagnesium iodide solution
3-Thienylmagnesium iodide solution (CAS: 172035-86-8) is an organometallic reagent with the empirical formula C4H3IMgS and a molecular weight of 234.34 g/mol. Supplied as a 0.3 M solution in Tetrahydrofuran (THF), this Grignard reagent is characterised by its reactivity. It is primarily utilised in organic synthesis for introducing the 3-thienyl moiety into various molecular structures, particularly in the development of pharmaceuticals and advanced materials.
Organic Synthesis
Serves as a key Grignard reagent for the formation of carbon-carbon bonds, enabling the introduction of the 3-thienyl group into organic molecules. It is instrumental in the synthesis of complex heterocycles and functionalised thiophene derivatives.
Pharmaceutical Intermediate
Used in the multi-step synthesis pathways for active pharmaceutical ingredients (APIs) where a thienyl ring is a core structural component. Facilitates the construction of novel drug candidates.
Materials Science
Enables the preparation of novel organic electronic materials, including conductive polymers and organic semiconductors, by incorporating the thiophene unit known for its electronic properties.
