Product Description:
a-Naphtholphthalein is used as a pH indicator and operates in the pH ranges between 7.3 and 8.7.
Optical carbon dioxide sensor based on the colorimetric change of pH indicator a-naphtholphthalein with the internal reference fluorescent CIS/ZnS qua.It is also used in the designing of optical carbon dioxide sensor based on fluorescence intensity.a-Naphtholphthalein has been described for use in the design of an optical CO2 sensor based on the fluorescence intensity changes of Tetraphenylporphyrin (sc-215304) due to absorption changes of alpha-Naphtholphthalein embedded in a polymer.

Methylthymol blue is a Water soluble chelometric indicator.Methylthymol blue (MTB) is a metal- lochromic indicator which forms metal complexes different in spectral absorption characteristics from the free indicator. The barium complex is formed at relatively high pH with maximum absorption at 608 nm; free MTB at the same pH has a maximum absorption at 460nm.
METHYL THYMOL BLUE COMPLEXONE Product Description: Thymol blue (thymolsulfonephthalein) is a brownish-green or reddish-brown crystalline powder that is used as a pH indicator. It is insoluble in water but soluble in alcohol and dilute alkali solutions.
