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.
The molecular formula C 7 H 5 NO 3 (molar mass: 151.12 g/mol, exact mass: 151.0269 u) may refer to: 2-Nitrobenzaldehyde; 3-Nitrobenzaldehyde; 4-Nitrobenzaldehyde
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.
