Beschreibung
Sodium sulphate R₁ anhydrous is a solid pharmacopoeia reagent (Reag. Ph. Eur., Chapter 4.1.1, 1083801) with CAS number 7757-82-6, empirical formula Na₂SO₄ and molar mass 142,04 g/mol. The anhydrous material is supplied in a 100 g pack and has a density of 2,7 g/cm³. It is intended for laboratory use as the European Pharmacopoeia reagent sodium sulphate R₁, supporting analytical and quality-control work that cites Chapter 4.1.1 reagents of this identity. Identity data from manufacturer Carl ROTH include EG number 231-820-9, allowing the salt to be recorded consistently in reagent inventories and method documentation. The 100 g presentation is suitable for laboratories that require a defined anhydrous sodium sulphate for pharmacopoeial testing without committing to bulk quantities. Molar mass and density support stoichiometric and volumetric calculations when the solid is weighed or when packing volume is considered. As a named Reag. Ph. Eur. item, the product provides a clearly specified anhydrous sodium sulphate R₁ for procedures that call for this grade and chapter reference.
