3-Hydroxyphenylboronic acid（Cat No.:L023838）, also known as meta-hydroxyphenylboronic acid, is an aromatic boronic acid featuring a hydroxyl group at the meta-position relative to the boronic acid moiety. It is a white to off-white crystalline solid commonly used in Suzuki-Miyaura cross-coupling reactions for forming carbon–carbon bonds in organic synthesis. The hydroxyl group influences both the reactivity and solubility of the molecule, enabling selective functionalization and hydrogen bonding. This compound is useful in the synthesis of pharmaceuticals, agrochemicals, and advanced materials, and is also explored in sensor development and molecular recognition studies.
