Chemical Properties

beige powder

Definition

ChEBI: A monocarboxylic acid comprising acetic acid substituted at the alpha carbon with a 2-nitrophenoxy group.

Purification Methods

Crystallise the acid from water, and dry it over P2O5 in vacuo. The S-benzylisothiuronium salt has m 155-156o (from EtOH). [Hayes & Brooch J Am Chem Soc 65 1577 1943, Beilstein 6 H 220, 6 II 211, 6 III 804, 6 IV 1261.]
