Description
Methyl red indicator solution is a ready-to-use 0,1 % preparation in denatured ethanol for titration and pH indication. Physical data include a density of 0,79 g/cm³, a flash point of 13 °C, a boiling point of 78 °C, and UN number 1170, reflecting the ethanolic solvent system. This format belongs to ready-to-use pH indicator solutions used in volumetric analysis when an alcoholic methyl red medium is specified. The denatured-ethanol matrix is familiar in classical analytical procedures and teaching laboratories. Laboratories performing acid–base titrations that call for methyl red in ethanol benefit from the pre-adjusted 0,1 % strength and the convenient glass bottle presentation. Handling should respect the flammable nature indicated by the flash point and UN classification, in line with normal solvent-indicator practice on the analytical bench.
This article is part of Indicators & indicator solutions, in Analytical standards & reference materials.

Questions about Methyl red indicator solution, 0,1 % in ethanol, denatured, 250 ml, glass
What is this article?
Methyl red indicator solution, 0,1 % in ethanol, denatured, 250 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Indicators & indicator solutions, inside Analytical standards & reference materials, in Lab chemicals.
An indicator solution changes colour at a stated point, usually a pH interval or a redox potential, so a titration endpoint can be seen. The solvent and the concentration decide how sharp the change is. A solid indicator dye and a ready solution are different articles.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.

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.
