Potassium chromate solution, Reag. Ph. Eur., Chapter 4.1.1, 1 l

Potassium chromate solution is a pharmacopoeia reagent designated Reag. Ph. Eur., Chapter 4.1.1, 1069201. It is based on potassium chromate, CAS number 7789-00-6, empirical formula K₂CrO₄ and molar mass 194,21 g/mol. The ready-to-use aqueous solution is supplied in a 1 l pack, with a density of approximately 1 g/cm³ and a boiling point of 100 °C. These physical values help laboratories plan dispensing, glassware choice and any heating steps. As a Chapter 4.1.1 reagent, the product is intended for analytical procedures that specify European Pharmacopoeia reagents, including pharmaceutical quality-control work. Using a prepared solution removes the need to weigh solid potassium chromate and to compound the monograph reagent in house. The preparation from manufacturer Carl ROTH sits in the range of chemicals in pharmacopoeia quality and of Ph. Eur. reagents and volumetric standard solutions. The 1 l volume suits repeated bench use. EG number 232-140-5 identifies the chromate constituent, and UN number 3082 applies to transport of the solution.
