LabChem® Thymolphthalein 0.1% In Ethanol, 125mL

LabChem® THYMOLPHTHALEIN 0.1% in Ethanol is a 0.1% ethanolic solution of thymolphthalein, a pH indicator that transitions from colorless in acid to blue in base over an approximate pH range of 9.3 to 10.5. It is manufactured to consistent purity and concentration for reliable, reproducible color response. Its transition range, higher than phenolphthalein, makes it useful for titrations requiring a more alkaline endpoint.

It is commonly used as a pH indicator in acid-base titrations requiring a distinctly alkaline endpoint. Its consistent formulation supports reliable, reproducible color transitions across preparations. This reagent should be handled, stored, and used according to established laboratory safety procedures and the manufacturer's instructions.
