Ammonium iron(III) sulphate solution R2

Ammonium iron(III) sulphate solution R2 is a pharmacopoeia-quality laboratory reagent corresponding to Reag. Ph. Eur., Chapter 4.1.1, reference 1037702. It provides the defined R2 reagent required by European Pharmacopoeia procedures that cite ammonium iron(III) sulphate solution R2 in chapter 4.1.1. The solution has a density of approximately 1 g/cm³ and a boiling point of 100 °C. The product is supplied in a 1 liter pack with a weight of 1,200 kg, a practical volume for repeated analytical work. This solution is available from manufacturer Carl ROTH as part of the assortment of chemicals in pharmacopoeia quality and of reagents and volumetric standard solutions according to Ph. Eur. Selecting the R2 designation helps laboratories match the exact reagent named in monographs and general methods, rather than a different R-numbered ammonium iron(III) sulphate solution. The preparation is suitable for pharmaceutical analysis, pharmacopoeial testing and related quality-control laboratories that follow European Pharmacopoeia reagent specifications. Physical constants support identification and routine handling of the liquid reagent. Chapter 4.1.1 grouping places the article among official Ph. Eur. reagents used to standardise analytical practice across laboratories.
