Product Description:

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.
