Potassium hydroxide solution in ethanol (0,5 mol/l – 0,5 N) is a non-denatured volumetric solution conforming to Reag. Ph. Eur. for analytical and titration work. Identified by CAS number 1310-58-3, empirical formula KOH and molar mass 56,11 g/mol, this ethanolic KOH reagent provides a defined normality for pharmaceutical, chemical and quality-control laboratories. Physical data include a density of approximately 0,842 g/cm³, a flash point of 12 °C and a boiling point around 78 °C, consistent with the ethanol solvent system. The ready-to-use 1 l pack supports routine volumetric analysis, standardisation and method protocols that specify undenatured ethanolic potassium hydroxide. Prepared as a volumetric solution from manufacturer Carl ROTH, it integrates smoothly into pharmacopoeial and general laboratory workflows where a stable 0,5 N ethanolic base is required. Its non-denatured character helps maintain method consistency whenever undenatured ethanol media are stipulated, reducing preparation steps when the stated concentration matches the analytical procedure.
