Potassium hydroxide solution in ethanol R1

Potassium hydroxide solution in ethanol R₁ is a reagent of pharmacopoeia quality (Reag. Ph. Eur., Chapter 4.1.1, 1070304) identified by CAS number 1310-58-3, empirical formula KOH and molar mass 56,11 g/mol. Prepared as an ethanolic solution of potassium hydroxide, it is listed among European Pharmacopoeia reagents for Chapter 4.1.1 and carries the Ph. Eur. reference 1070304. The 1 liter pack is intended for analytical laboratories that follow pharmacopoeial methods requiring this designated reagent R₁. Density is approximately 0,8 g/cm³, the flash point is 16 °C and the boiling point is 78 °C, consistent with an ethanol-based matrix. EG number 215-181-3 further identifies the potassium hydroxide component for documentation and goods-receipt control. This preparation from manufacturer Carl ROTH supports monograph testing, identification procedures and other Ph. Eur. workflows that specify potassium hydroxide solution in ethanol R₁, and is assigned UN number 2924. Use the solution in accordance with the relevant pharmacopoeial chapter and established laboratory practice. Quality systems can record the CAS number, EG number and Ph. Eur. designation together with the 1 liter pack size for traceability.
