Cas no 1256359-04-2 (2-Chloro-4-fluoropyridine-5-boronic acid, pinacol ester)

2-Chloro-4-fluoropyridine-5-boronic acid pinacol ester is a versatile boronic acid derivative commonly employed in Suzuki-Miyaura cross-coupling reactions. Its pinacol ester group enhances stability, improving handling and storage compared to the free boronic acid form. The chloro and fluoro substituents on the pyridine ring provide reactive sites for further functionalization, making it a valuable intermediate in pharmaceutical and agrochemical synthesis. The compound's compatibility with a wide range of coupling partners and its moderate reactivity contribute to its utility in constructing complex heterocyclic frameworks. Its crystalline solid form ensures consistent purity and ease of quantification in synthetic applications.
