Description
Bromothymol blue solution R4 is a pharmacopoeia-quality reagent specified as Reag. Ph. Eur., Chapter 4.1.1, 1012904. This 100 ml solution is intended for laboratory procedures that call for bromothymol blue solution R4 according to the European Pharmacopoeia. The liquid shows a density of approximately 0,9 g/cm³, a flash point of about 24 °C and a boiling point of 78 °C. Pack size is 100 ml and the stated weight is 0,200 kg. Physical constants and UN number 1993 are given by manufacturer Carl ROTH. The product belongs to the Reagents 4.1.1 series within chemicals in pharmacopoeia quality, used together with reagents and volumetric standard solutions (Ph. Eur.). The ready-to-use 100 ml presentation is suited to analytical, quality-control and research laboratories that work to Chapter 4.1.1. Density, flash point and boiling point should be observed during transfer, mixing and disposal. Bromothymol blue solution R4 provides a defined Ph. Eur. reagent for professional chemical and pharmaceutical laboratory workflows that require the R4 solution described in the pharmacopoeia.

Questions about Bromothymol blue solution R4, Reag. Ph. Eur.
What is this article?
Bromothymol blue solution R4, Reag. Ph. Eur. 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.
