Description
Potassium hydroxide solution in ethanol is a 0,1 mol/l (0,1 N) volumetric solution of KOH in 96 % non-denatured ethanol, designated Reag. Ph. Eur. for pharmacopoeial and analytical titration work. Based on potassium hydroxide (CAS 1310-58-3, empirical formula KOH, molar mass 56,11 g/mol), the ethanolic medium shows a density of approximately 0,827 g/cm³, flash point 12 °C and boiling point around 78 °C. Packaged as 1 liter, this ready-to-use volumetric reagent supports non-aqueous or mixed-solvent titrations, saponification-related assays and standardisation tasks where an alcoholic KOH titre is specified. The solution from manufacturer Carl ROTH carries EG nr. 215-181-3 and is formulated for laboratories that require defined ethanolic base strength without preparing solid KOH in ethanol on site. Suitable for pharmaceutical, chemical and quality-control environments working under Ph. Eur. reagent expectations for volumetric potassium hydroxide in ethanol.

Questions about Potassium hydroxide solution in ethanol
What is this article?
Potassium hydroxide solution in ethanol is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
