oxalic acid usage and synthesis

chemical properties	white crystalline powder
usage	an impurity of oxaliplatin which is a coordination complex that is used in cancer chemotherapy.
general description	odorless white solid. sinks and mixes with water.
air & water reactions	water soluble. hygroscopic
reactivity profile	oxalic acid is hygroscopic and sensitive to heat. oxalic acid may react violently with furfuryl alcohol, silver, sodium, perchlorate, sodium hypochlorite, strong oxidizers, sodium chlorite, acid chlorides, metals and alkali metals. . the heating of mixtures of oxalic acid and urea has lead to explosions. this is due to the rapid generation of the gases, co2, co, and nh3, [praxis naturwiss. chem., 1987, 36(8), 41-42]. oxalic acid and urea react at high temperatures to form toxic and flammable ammonia and carbon monoxide gasses, and inert co2 gas [von bentzinger, r. et al., praxis naturwiss. chem., 1987, 36(8), 41-42].
health hazard	as dust or as a solution, can cause severe burns of eyes, skin, or mucous membranes. ingestion of 5 grams has caused death with symptoms of nausea, shock, collapse, and convulsions coming on rapidly. repeated or prolonged skin exposure can cause dermatitis and slow-healing ulcers.
fire hazard	special hazards of combustion products: generates poisonous gases
