3-Ethylaniline (m-Ethylaniline) is an important aromatic amine intermediate used in dye synthesis, pharmaceutical manufacturing, and agrochemical production. This compound has a density of 0.975 g/mL at 25°C, boiling point of 212°C (lit.), and refractive index of 1.555 (n20/D). It exhibits characteristic amine reactivity and is sensitive to air/light, requiring storage under nitrogen/inert atmosphere at 2-8°C. Safety precautions are essential due to toxicity (GHS06) and potential to form methemoglobin (GHS08). The ethyl group at the meta-position influences its electronic properties, making it valuable for synthesizing asymmetrical triarylmethane dyes and functional materials.
