Thymolphthalein solution is a pharmacopoeia reagent specified as Reag. Ph. Eur., Chapter 4.1.1, reference 1090701. The preparation is supplied in a 100 ml pack suitable for laboratory work that calls for this Chapter 4.1.1 reagent. Listed physical properties include a density of 0,79 g/cm³, a flash point of 12 °C and a boiling point of 78 °C, supporting documentation of handling and method conditions. This thymolphthalein solution comes from manufacturer Carl ROTH within the range of reagents and volumetric standard solutions of pharmacopoeia quality. UN number 1170 is assigned to the article together with the stated density, flash point and boiling point. Laboratories following European Pharmacopoeia Chapter 4.1.1 can use the 100 ml presentation wherever reagent 1090701 is required. The combination of Reag. Ph. Eur. identity, defined pack size and published physical constants—density 0,79 g/cm³, flash point 12 °C, boiling point 78 °C—provides a clear specification for receipt, handling and analytical use of this thymolphthalein solution.
This article is part of Reagents for analysis (Ph. Eur., ASTM, DIN), in Analytical standards & reference materials.

Questions about Thymolphthalein solution, Reag. Ph. Eur., Chapter 4.1.1, 100 ml
What is this article?
Thymolphthalein solution, Reag. Ph. Eur., Chapter 4.1.1, 100 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reagentia voor analyse (Ph. Eur., ASTM, DIN), inside Analytische standaarden & referentiematerialen, in Chemicaliën.
A reagent for analysis is a chemical whose impurities are limited so they do not become a signal in a titration, a digestion or a photometric method. Pharmacopoeia, ASTM and DIN names point at different limit lists. The grade, not only the identity, is the purchase.
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.
