 Copper oxalate (CAS NO.814-91-5) is also named as Caswell No. 248A ; Copper oxalate (CuC₂O₄) ; Copper(II) oxalate ; Cupric oxalate ; Cupric oxalate (1:1) ; EPA Pesticide Chemical Code 023305 ; Ethanedioic acid copper salt ; Ethanedioic acid, copper(2+) salt (1:1) ; HSDB 265 ; NSC 112246 ; NSC 86015 ; Oxalic acid copper(2+) salt (1:1) ; Copper, (ethanedioato(2-)-kappaO1,kappaO2)- . Copper oxalate (CAS NO.814-91-5) is odorless bluish-white solid. Cupric oxalate dissolves in aqueous ammonia and reacts as an acid to neutralize other bases as well. It can serve as a reducing agent in reactions that generate carbon dioxide. Inhalation causes irritation of nose and throat. Ingestion of very large amounts may produce symptoms of oxalate poisoning; watch for edema of the glottis and delayed constriction of esophagus. Contact with eyes causes irritation. It may form toxic carbon monoxide gas in fire.
