Ammonium nitrate solution is a volumetric standard solution at 1 mol/l (1 N) for analytical titration and quantitative laboratory applications. It is identified by CAS number 6484-52-2, EG nr. 229-347-8 and the empirical formula NH₄NO₃, with a molar mass of 80,04 g/mol. The aqueous preparation has a density of 1,03 g/cm³ and a boiling point of 100 °C. Delivered in a 1 l pack, it provides a defined normality for standardized volumetric work without intermediate dilution when methods specify 1 mol/l – 1 N ammonium nitrate. This reagent is offered by manufacturer Carl ROTH as part of its volumetric standard solutions range for analytical chemistry laboratories. Ready-made concentration control supports reproducible titrimetric procedures and reduces variability associated with manual solution preparation. The 1 litre unit quantity is practical for repeated analytical series and routine quality-control workflows. Molar mass, density and boiling-point data support method documentation and safe handling. This ammonium nitrate volumetric standard solution is suited to laboratories that require a reliable, pre-standardized nitrate reagent for quantitative analysis.
