Ammonium nitrate AR is a high-purity analytical reagent used primarily in laboratories for chemical analysis, fertilizer production, and as an oxidizer in controlled reactions. It is a white crystalline solid with a high nitrogen content, ensuring reliable and consistent results in research and industrial applications. Industrially, ammonium nitrate is chiefly used to make nitrogen fertilizers and industrial and military explosives, and also serves in nitrous oxide production, pyrotechnics and as a propellant oxidizer. This chemical has a CAS number of 6484-52-2, with the molecular formula H4N2O3 and a molecular weight of 80.04 g/mol. It is stable at ambient storage conditions but requires careful handling, as indicated by its warning signal word. Molekula supplies Ammonium nitrate AR from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
