Description
Bromothymol blue solution R1 is a European Pharmacopoeia reagent specified as Reag. Ph. Eur., Chapter 4.1.1, reagent 1012901, supplied in a 100 ml pack. The solution is intended for laboratories that maintain chemicals in pharmacopoeia quality and that work with reagents and volumetric standard solutions according to Ph. Eur. Density is ~1 g/cm³, the flash point is ~40 °C and the boiling point is 100 °C; UN number 1993 applies. Unit quantity is 100 ml and the listed weight is 0,200 kg, a compact presentation for Chapter 4.1.1 reagent sets. This preparation is available from manufacturer Carl ROTH as bromothymol blue solution R1 matching pharmacopoeial reagent 1012901. Specifying the Reag. Ph. Eur. article supports protocols that cite Chapter 4.1.1 by number and require the R1 solution rather than an undefined bromothymol blue mixture. Density, flash point, boiling point and UN 1993 should be observed during handling and transport. The 100 ml format suits routine analytical work in environments that document reagents against the European Pharmacopoeia.

Questions about Bromothymol blue solution R1
What is this article?
Bromothymol blue solution R1 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.
