3-Methoxydiphenylamine is an important aromatic amine compound primarily used in the synthesis of diazonium salts (MDP-4-DS) and diazoresins for dye manufacturing. It features a melting point of 72-74°C and boiling point of 160°C (2 mmHg). The compound has a density of 1.11 g/cm³ and exhibits sensitivity to air. As a key intermediate, it finds applications in dyes, stains, indicators, and industrial processes. Storage should be in airtight containers under inert gas, protected from light. Safety precautions include wearing protective gloves/eyewear due to potential skin/eye irritation (GHS Category 2). Its molecular structure contains both methoxy and secondary amine functional groups, enabling diverse chemical transformations.
