Description
Water particle-free is a reagent water specified as Reag. Ph. Eur., Chapter 4.1.1 (1095507), with CAS number 7732-18-5 and empirical formula H₂O. This material has a molar mass of 18,02 g/mol, a density of 1 g/cm³ and a boiling point of 100 °C; it is also identified by EG nr. 231-791-2. The particle-free water is supplied in a 1 l glass bottle for laboratory use among reagents of the European Pharmacopoeia. It is grouped with Reagents 4.1.1 and with reagents and volumetric standard solutions (Ph. Eur.), so it can be selected wherever that chapter requires particle-free water. Typical laboratory tasks include preparing test solutions and supporting analytical procedures that cite this reagent. The item is offered by manufacturer Carl ROTH in the chemicals in pharmacopoeia quality range. Stated physical constants, including density and boiling point, allow straightforward identification and handling under ordinary laboratory conditions. The 1 l glass presentation suits routine dispensing while maintaining the named particle-free character of the reagent water.
