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

General Description

The 2-Nitrobenzyl group of 2-nitrobenzaldehyde is photolabile that can be cleaved when exposed to UV-light.

Purification Methods

Crystallise the aldehyde from toluene (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.]
