4-Nitrophenylacetic acid Chemical Properties,Uses,Production

Chemical Properties

Beige to yellow crystalline powder
4-Nitrophenylacetic acid is a member of the class of phenylacetic acids that is phenylacetic acid in which the phenyl grup is substituted at the para- position by a nitro group.

Uses

Intermediate for dyestuffs, pharmaceuticals, penicillin precursors, local anesthetics.

Uses

(4-Nitrophenyl)acetic Acid used in the synthesis of 5,7-dimethyl-2-aryl-3H-pyrrolizin-3-ones which may act as angiogenesis inhibitors. Also used in the one step construction of amino-substituted squaraine dye.

Definition

ChEBI: A monocarboxylic acid that is phenylacetic acid carrying a nitro substituent at position 4.

Safety Profile

Moderately toxic intraperitoneal route. Mutation data reported. When heated to decomposition it emits toxic vapors of NOx.

Purification Methods

Crystallise the acid from EtOH/water (1:1), then from sodium-dried diethyl ether and dry it over P2O5 in vacuo. The styphnate has m 196.5-197o (prisms from EtOH). The amide has m 191o (from EtOH). [Beilstein 9 III 2284, 9 IV 1698.]
