Description
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.

Questions about ortho-Phosphoric acid diluted R1, Reag. Ph. Eur., 1 l
What is this article?
ortho-Phosphoric acid diluted R1, Reag. Ph. Eur., 1 l is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acids, inside Acids & bases, in Lab chemicals.
An acid on this shelf is the substance itself, concentrated or as a stated solution: hydrochloric, sulfuric, nitric, acetic and the rest. Concentration, purity and the trace metals decide the use. A concentrated acid and a volumetric solution of the same name are different products, and both burn.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
