Beschreibung
ortho-Phosphoric acid diluted R₁ is a Reag. Ph. Eur. reagent prepared to Chapter 4.1.1 (1065102), corresponding to phosphoric acid with CAS number 7664-38-2, empirical formula H₃PO₄, molar mass 98,00 g/mol and EG nr. 231-633-2. Offered in a 1 liter pack, the diluted reagent has a density of approximately 1 g/cm³ and a boiling point of 100 °C. These physical values describe an aqueous R₁ preparation used in pharmacopoeial handling and test solutions. Quality-control and analytical laboratories use ortho-phosphoric acid diluted R₁ wherever the European Pharmacopoeia specifies this Chapter 4.1.1 reagent for identification work, limit tests and related monograph procedures. The product is available from manufacturer Carl ROTH as a 1 l unit for laboratory workflows that follow Ph. Eur. reagent texts. Formula H₃PO₄ and molar mass 98,00 g/mol identify the phosphoric acid component, while reference 1065102 links the item to the official reagent text. Together, the defined composition, density around 1 g/cm³ and 1 liter pack size support consistent use in Ph. Eur. reagent applications.
