Description
Bromothymol blue solution R2 is a pharmacopoeia-quality reagent specified as Reag. Ph. Eur., Chapter 4.1.1, reference 1012902. It is supplied as a 100 ml unit with a weight of 0,200 kg. The solution has a density of 0,95 g/cm³, a flash point of 57,5 °C and a boiling point of 153 °C, and is assigned UN number 2265. This named reagent from manufacturer Carl ROTH is listed among chemicals in pharmacopoeia quality and among reagents and volumetric standard solutions of the European Pharmacopoeia, specifically the Reagents 4.1.1 series. Laboratories that follow Ph. Eur. general methods can select Bromothymol blue solution R2 wherever Chapter 4.1.1 requires this R2 preparation rather than another bromothymol blue grade. The 100 ml pack size suits routine analytical benches that need a defined pharmacopoeial reagent volume, while the stated density, flash point and boiling point describe the physical behaviour of the liquid as supplied. Reference 1012902 identifies the Chapter 4.1.1 entry for Bromothymol blue solution R2.

Questions about Bromothymol blue solution R2
What is this article?
Bromothymol blue solution R2 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.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Indicators & indicator solutions. The catalogue is Lab chemicals.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Reference substances & reagents (other), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN) and Spectroscopy & physical property standards.
What should I check before I order?
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.
