Quid est O-Cresolphthaleinum CAS 596-27-0?

Phthaleinum O-cresoli est pulvis crystallinus albus vel pallide flavus. Punctum liquefactionis 216 ~ 217°C. Solubile in alcohole, aethere et acido acetico glaciali, leviter solubile in aqua, in benzeno insolubile, solubile in alcali diluto. In chemia analytica ut indicator acidi et basis adhibetur. Structuram chemicam et proprietates physicas et chemicas similes phenolphthalei habet, et eius discoloratio coloris inter 8.2 (incolor) et 9.8 (rubrum) est (intervallum discolorationis coloris phenolphthalei inter 8.2 et 10 est). Structura eius acida est forma lactonae incolorae, structura autem basis est forma quinonae, quae rubra apparet.
