Introduction to 2,6-Difluoro-4-formylphenylboronic acid (CAS No. 871125-93-8)

2,6-Difluoro-4-formylphenylboronic acid, identified by the Chemical Abstracts Service Number (CAS No.) 871125-93-8, is a specialized organic compound that has garnered significant attention in the field of pharmaceutical chemistry and materials science. This boronic acid derivative features a unique structural motif consisting of a phenyl ring substituted with two fluorine atoms at the 2- and 6-positions, and a formyl group at the 4-position. The presence of both fluorine atoms and a formyl group imparts distinct electronic and steric properties, making this compound a valuable intermediate in synthetic chemistry and a potential candidate for various applications.

The fluorine atoms in 2,6-Difluoro-4-formylphenylboronic acid play a crucial role in modulating the reactivity and selectivity of the compound. Fluorine is known for its ability to influence metabolic stability, binding affinity, and electronic properties of molecules.
