Description
Methylthymol blue is a pharmacopoeia-quality reagent (Reag. Ph. Eur., Chapter 4.1.1, 1158501) supplied as a trituration 1,100 with KNO3. The preparation has a density of 2,1 g/cm³ and is packed as 50 g in plastic. It belongs to the Reagents 4.1.1 group used with reagents and volumetric standard solutions (Ph. Eur.) in analytical and quality-control laboratories. The trituration with potassium nitrate (KNO3) corresponds to the form given for this Ph. Eur. reagent, so the material can be used where a methylthymol blue trituration 1,100 with KNO3 is specified. UN number 1486 is stated for the product. This 50 g plastic pack from manufacturer Carl ROTH offers a convenient quantity for preparing pharmacopoeial reagents and related laboratory mixtures. Density data of 2,1 g/cm³ help identify and handle the trituration in routine work. Laboratories following European Pharmacopoeia methods can match Chapter 4.1.1 and reference 1158501 when selecting methylthymol blue in this triturated form. The plastic 50 g presentation keeps the reagent available for repeated small-scale preparations consistent with the declared composition and pharmacopoeial listing.

Questions about Methylthymol blue, trituration 1,100 with KNO3
What is this article?
Methylthymol blue, trituration 1,100 with KNO3 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?
