Description and Uses
m-Cresol is employed in the preparation of synthetic resins like phenol-formaldehyde resins, disinfectants, and photographic developers. It is used as industrial solvent for dissolving polymers such as polyaniline. It acts as a precursor to vitamin E and antiseptic amylmetacresol. It is used as insuline preservatives.
