Hazard Information

Potential Exposure
It is used in chemical analysis and to make blueprint paper, explosives; a rust-removal ingredient in metal polishes.
First aid
Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
Shipping
UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN1759 Corrosive solids, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required.
Incompatibilities
Ammonium oxalate is a reducing agent and also reacts as a base to neutralize acids and reacts with oxidizers generating carbon dioxide. Incompatible with oxidizers (chlorates, hypochlorite solutions, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
Description
Ammonium oxalate, C2H8N2O4 (some times written as (NH4)2C2O4), is an oxalate salt with ammonium (sometimes as a monohydrate). It is a constituent of some types of kidney stone. Found also in guano.
Chemical Properties
Ammonium oxalate is an odorless, colorless crystalline material or powder.
Definition
ChEBI: An ammonium salt consisting of ammonium and oxalate ions in a 2:1 ratio.
