Description

4-Iodophenol (CAS No. 540-38-5) is a high-purity aromatic organic compound with the molecular formula C₆H₅IO, widely utilized in pharmaceutical, agrochemical, and material science research. This crystalline solid, also known as p-Iodophenol or 4-Hydroxyiodobenzene, serves as a versatile intermediate in Suzuki coupling reactions, electrophilic substitutions, and as a precursor for liquid crystal materials. With a molecular weight of 220.01 g/mol, it exhibits excellent reactivity due to the electron-withdrawing iodine substituent on the phenolic ring. Our product is rigorously tested to ensure ≥98% purity (HPLC) and is supplied in amber glass vials under inert conditions to prevent degradation. Ideal for controlled synthesis of advanced organic molecules, 4-Iodophenol is a must-have for researchers developing bioactive compounds or functional materials.

Application

4-Iodophenol is a key building block in organic synthesis, particularly in cross-coupling reactions to form biaryl structures for pharmaceuticals. It is employed in the preparation of liquid crystals and OLED materials due to its stable iodinated aromatic core. Researchers also use it as a derivatization agent in analytical chemistry for detecting trace phenols.
