Description
Bromophenol blue indicator solution is a ready-to-use pH indicator preparation containing 0,1 % bromophenol blue in denatured ethanol. It shows a density of 0,79 g/cm³, a flash point of 12 °C and a boiling point of 78 °C, and is classified under UN number 1170. The solution is intended for titration and pH indication work where a clear colour transition is required in acidic ranges. Packed in a 100 ml plastic bottle, it is convenient for bench-top use in analytical and teaching laboratories. As a pre-dissolved indicator from manufacturer Carl ROTH, it eliminates the need to prepare ethanolic stock solutions on site and supports consistent endpoint detection. Typical applications include acid–base titrations and visual pH monitoring within the established colour-change interval of bromophenol blue. The compact pack size suits method validation, student practicals and routine quality-control titrations that rely on reliable indicator response.
This article is part of Indicators & indicator solutions, in Analytical standards & reference materials.

Questions about Bromophenol blue indicator solution, 0,1 % in ethanol denatured, 100 ml, plastic
What is this article?
Bromophenol blue indicator solution, 0,1 % in ethanol denatured, 100 ml, plastic 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.
