Beschrijving
Water ammonium-free is reagent-quality water according to Reag. Ph. Eur., Chapter 4.1.1 (1095501), with CAS number 7732-18-5 and empirical formula H₂O. Molar mass is 18,02 g/mol, density is 1 g/cm³ and boiling point is 100 °C. The product is packed as 1 l in plastic. Ammonium-free water from manufacturer Carl ROTH is used where pharmacopoeial reagents of Chapter 4.1.1 require water that is free from ammonium for tests and preparations. It belongs to chemicals in pharmacopoeia quality, specifically reagents and volumetric standard solutions (Ph. Eur.) under Reagents 4.1.1. Laboratories employ this grade when an unspecified water would not meet the ammonium-free stipulation of the monograph or reagent recipe. The 1 l plastic pack suits bench-scale preparation of reagents and related aqueous solutions. Physical data for H₂O are molar mass 18,02 g/mol, density 1 g/cm³ and boiling point 100 °C, as stated for this material. Water ammonium-free, Reag. Ph. Eur., Chapter 4.1.1, thus supplies a defined 1 l quantity of ammonium-free water for pharmacopoeial laboratory work identified by CAS 7732-18-5.
