Metacresol purple - Wikipedia

Metacresol purple or m-cresol purple, also called m-cresolsulfonphthalein is a triarylmethane dye and a pH is used as a capnographic indicator for detecting detect end-tidal carbon dioxide to ensure successful tracheal intubation in an emergency. It can be used to measure the pH in subzero temperatures of saline or hypersaline media.
