2-Nitrobenzaldehyde is an intermediate in an early route to indigo, a water-insoluble dye commonly used to dye jeans and other fabrics.In the Baeyer-Drewson indigo synthesis, 2-nitrobenzaldehyde condenses with acetone in basic aqueous solution to yield indigo in a one-pot synthesis [9] [10] The method was abandoned in the early part of the 20th century, being replaced by routes from aniline.
3-Nitrobenzaldehyde is an organic compound with the formula O 2 NC 6 H 4 CHO. It is one of three isomers of nitrobenzaldehyde. It contains a nitro group meta-substituted to the aldehyde. 3-Nitrobenzaldehyde is the primary product obtained via the mono-nitration of benzaldehyde with nitric acid. [3] C 6 H 5 CHO + HNO 3 → O 2 NC 6 H 4 CHO + H 2 O
The Baeyer–Drewsen indigo synthesis (1882) is an organic reaction in which indigo is prepared from 2-nitrobenzaldehyde and acetone [1] [2] The reaction was developed by von Baeyer and Viggo Drewsen in 1880 to produce the first synthetic indigo at laboratory scale. This procedure is not used at industrial scale.

Amygdalin 2 H 2 O HCN benzaldehyde 2 × glucose 2 × Benzaldehyde contributes to the scent of oyster mushrooms (Pleurotus ostreatus). Reactions Benzaldehyde is easily oxidized to benzoic acid in air at room temperature, causing a common impurity in laboratory samples. Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. Benzyl ...
