Used in the synthesis of dyes and pigments, particularly in hair coloring products due to its ability to form stable color compounds through oxidative coupling. It acts as a coupler in combination with primary intermediates like p-phenylenediamines, enhancing shades such as reds, violets, and blues. Compared to other aminophenols, it offers reduced irritation, making it suitable for cream or lotion formulations that are gentle on the scalp. Also employed in the development of photographic chemicals and certain pharmaceutical intermediates where substituted aminophenols are required. Its methoxy and amino groups contribute to solubility and reactivity in aqueous and organic formulations.
