Recently Cresol Red has been used as a pH sensitive indicator dye in nanoengineered optical urea biosensors films and hetero-core structured fiber optic pH sensor. This work describes the physical–chemical characteristics of purified cresol red for use in measurements of seawater pH over a range of temperatures and salinities. A pH sensor based on the immobilisation of cresol red in the anionic Dowex 1×10 resin and its analytical potential in pH measurement is described. In agarose, Cresol Red runs with an apparent molecular size of approx.
