Description
Indicator bromocresol green/methyl red is a mixed indicator reagent of pharmacopoeia quality, specified as Reag. Ph. Eur., Chapter 4.1.1, 1012602. Offered as a 100 ml solution, it is intended for laboratory work in which the European Pharmacopoeia requires the bromocresol green/methyl red indicator. Density is 0,78 g/cm³, the flash point is 18 °C and the boiling point is 78 °C. The pack contains 100 ml and the stated weight is 0,200 kg. These physical data, together with UN number 1170, come from manufacturer Carl ROTH. The preparation is part of the Reagents 4.1.1 range of chemicals in pharmacopoeia quality, used with reagents and volumetric standard solutions (Ph. Eur.). The 100 ml pack is suited to analytical, quality-control and research laboratories that follow Chapter 4.1.1. Density, flash point and boiling point should be taken into account when transferring or disposing of the liquid. This bromocresol green/methyl red indicator provides a defined Ph. Eur. reagent for professional chemical and pharmaceutical laboratory workflows.

Questions about Indicator bromocresol green/methyl red, Reag. Ph. Eur.
What is this article?
Indicator bromocresol green/methyl red, 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.
