PHENOLPHTHALEIN SOLUTION107238 Merck

Product Overview: Phenolphthalein Solution 1% Code 107238 Merck

Phenolphthalein Solution 1%, offered under catalogue code 107238 by Merck KGaA, is a ready-to-use analytical grade acid-base pH indicator designed for high accuracy titrimetric analysis. The active chemical compound features the molecular formula C20H14O4 and a molecular weight of 318.32 g/mol. Formulated as a stabilized 1 percent solution in an ethanolic matrix, it provides an exceptionally clear transition interval between pH 8.2 (colorless) and pH 10.0 (vibrant pink to violet-red). This precise visual endpoint identification eliminates user ambiguity and measurement error, making it a benchmark reagent for neutralization titrations, chemical quality control laboratories, pharmaceutical assays, wastewater monitoring, and academic educational institutions.
