Description
Mixed indicator methyl orange / bromocresol green is a mixed indicator reagent of Reag. Ph. Eur. quality according to Chapter 4.1.1, listed as 1054801. It combines methyl orange and bromocresol green in a liquid preparation for pharmacopoeial reagent use in analytical laboratories. The product is offered in a 100 ml plastic pack with a reported density of approximately 1 g/cm³ and a boiling point of 100 °C. This mixed indicator from manufacturer Carl ROTH supports European Pharmacopoeia workflows that call for the methyl orange / bromocresol green system under reagents 4.1.1. Chapter 4.1.1 of the European Pharmacopoeia lists this mixed indicator among reagents used in official analytical methods. The 100 ml plastic bottle suits volumetric analysis and quality-control titration work that specifies this mixed indicator. Density of about 1 g/cm³ and a boiling point of 100 °C characterise the physical properties of the solution as supplied for laboratory use. Analytical and quality-control laboratories working to Ph. Eur. Chapter 4.1.1 can employ the reagent wherever the method requires mixed indicator methyl orange / bromocresol green for acid-base indication in volumetric procedures.

Questions about Mixed indicator methyl orange / bromocresol green, 100 ml
What is this article?
Mixed indicator methyl orange / bromocresol green, 100 ml 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.
