Beschreibung
Phenol red solution R₂ is a Reag. Ph. Eur. reagent according to Chapter 4.1.1 (reference 1063603), supplied as a 100 ml plastic pack. Chemical identity is defined by CAS number 143-74-8, EG number 205-609-7 and the empirical formula C₁₉H₁₄O₅S; the molar mass is 354,38 g/mol. Listed physical data include a density of approximately 1 g/cm³ and a boiling point of 100 °C for this preparation. The 100 ml unit has a weight of 0,200 kg. This phenol red solution R₂ from manufacturer Carl ROTH supports laboratory work that follows European Pharmacopoeia reagents in Chapter 4.1.1 and that specifies the R₂ solution. Formula C₁₉H₁₄O₅S and CAS number 143-74-8 allow matching to pharmacopoeial and inventory records, while the molar mass of 354,38 g/mol can be cited in analytical documentation. Density near 1 g/cm³ and a boiling point of 100 °C complete the available characterisation. The 100 ml plastic presentation provides a practical volume for Ph. Eur. reagent collections that call for phenol red solution R₂ under reference 1063603.
