2-Nitrobenzaldehyde Usage And Synthesis

Chemical Properties	YELLOW CRYSTALLINE POWDER OR NEEDLES
Uses	2-Nitrobenzaldehyde is a benzaldhyde with a nitro group substituted in the ortho position. 2-Nitrobenzaldehyde is used in the preparation of dyes and colorants such as Indigo carmine. 2-Nitrobenzaldeh yde gas been shown to be a useful photoremovable protecting group as well as in the preparation of more effective ones such as o-Nitrophenylethylene glycol.
Definition	ChEBI: Benzaldehyde substituted at the ortho-position with a nitro group.
Synthesis Reference(s)	Synthetic Communications, 19, p. 3385, 1989 DOI: 10.1080/00397918908052745
Purification Methods	Crystallise the aldehyde from toluen e (2-2.5mL/g) by addition of 7mL pet ether (b 40-60o) for 1mL of solution. It can also be distilled under reduced pressures. [Beilstein 7 IV 584.]
