Thermo Scientific™ 4-Nitroanisole 99+%

4-Nitroanisole (para-nitroanisole) is a high-purity nitroaromatic compound commonly used as an intermediate in the synthesis of dyes, pigments, and pharmaceuticals. It features a nitro group positioned para to the methoxy group on a benzene ring, making it highly reactive in electrophilic aromatic substitution and nucleophilic aromatic substitution reactions.

Supplied at ≥99% purity (by GC), Thermo Scientific™ 4-Nitroanisole is ideal for research and industrial applications where high analytical precision is required. The compound appears as green to brown crystalline solid, stable under ambient conditions. Its high purity and defined melting range make it suitable for use in reaction development, fine chemical manufacturing, and compound characterization.
