Cas no 1109284-49-2 (methyl 5-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thiophene-2-carboxylate)

Methyl 5-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thiophene-2-carboxylate is a boronic ester derivative featuring a thiophene carboxylate core, commonly employed in Suzuki-Miyaura cross-coupling reactions. The presence of the pinacol boronate group enhances stability and reactivity, making it a valuable intermediate in pharmaceutical and materials science applications. The methyl ester functionality provides additional versatility for further derivatization. Its well-defined structure ensures consistent performance in synthetic transformations, while the thiophene scaffold contributes to electronic and optoelectronic applications. This compound is particularly useful in constructing complex heterocyclic systems with high precision. Proper handling under inert conditions is recommended to preserve its reactivity.
