Beschrijving
Phenolphthalein solution is a pharmacopoeia-quality chemical reagent specified as Reag. Ph. Eur., Chapter 4.1.1, reference 1063702. It is supplied as a 100 ml solution for laboratories that work according to European Pharmacopoeia reagent Chapter 4.1.1. Density is given as 0,82 g/cm³, the flash point as 17 °C and the boiling point as 78 °C, so the principal physical constants are available for handling, labelling and method documentation. The 100 ml unit quantity has a listed weight of 0,200 kg, a practical volume for pharmacopoeial reagent benches and for laboratories that keep Chapter 4.1.1 reagents in stock. This phenolphthalein solution from manufacturer Carl ROTH belongs to the range of chemicals in pharmacopoeia quality and of reagents and volumetric standard solutions (Ph. Eur.). The product is intended for chemical and pharmaceutical laboratories that specify phenolphthalein solution according to Chapter 4.1.1. Density, flash point and boiling point should be observed in the laboratory’s own procedures when the solution is taken into service.
This article is part of Indicators & indicator solutions, in Analytical standards & reference materials.

Questions about Phenolphthalein solution, Reag. Ph. Eur., 100 ml
What is this article?
Phenolphthalein solution, Reag. Ph. Eur., 100 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Indicatoren & indicatoroplossingen, inside Analytische standaarden & referentiematerialen, in Chemicaliën.
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.
