Thymolphthalein
CAS 125-20-2
White crystalline powder. Soluble in ether, acetone, sulfuric acid and alkali solution, insoluble in water. It is often used as an indicator of acid and alkali, with a pH change range of 9.4-10.6 and a color change from colorless to blue. It is often used to prepare 0.1% 90% ethanol solution. It is also often combined with other indicators to form a gentle indicator, making its color change range narrower and observation clearer.
