Beschreibung
Water CO2-free is carbon dioxide-free reagent water specified as Reag. Ph. Eur., Chapter 4.1.1, 1095502. It is chemically water (empirical formula H₂O) with CAS number 7732-18-5 and EG nr. 231-791-2, a molar mass of 18,02 g/mol, a density of 1 g/cm³ and a boiling point of 100 °C. The reagent is supplied in a 1 l plastic pack for use in laboratories that work according to the European Pharmacopoeia. Chapter 4.1.1 covers reagents required for pharmacopoeial tests, and this CO2-free grade is the water quality called for when dissolved carbon dioxide would interfere with the analytical result. Quality-control and analytical laboratories can employ the 1 l presentation for the preparation of solutions and for procedures that explicitly require carbon dioxide-free water. The product comes from manufacturer Carl ROTH within the Reag. Ph. Eur. reagent range. With clearly stated identity, physical constants and pharmacopoeial designation, Water CO2-free provides a defined H₂O reagent for routine pharmacopoeial work. The plastic 1 l pack is practical for benchtop use while remaining aligned with the Chapter 4.1.1 specification 1095502.
