Description
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.

Questions about Potassium hydroxide solution in ethanol R1
What is this article?
Potassium hydroxide solution in ethanol R1 is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Bases & alkalis, inside Acids & bases, in Lab chemicals.
A base or an alkali is sodium hydroxide, potassium hydroxide, ammonia and their relatives, as solid or as solution. The carbonate that a hydroxide picks up from the air changes a titre. Concentration and purity are the specification. Concentrated alkalis attack skin and aluminium.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
Which category should I open next?
