9-Methylfluorene was tested as an indicator in the titration of commonly used organometallic reagents. This indicator is readily prepared in three steps from fluorenone. In THF solution the deprotonated indicator is red and exhibits a sharp endpoint.

Role of Frontier Molecular Orbital Symmetry of Reagents in Redox Catalytic Indicator Reactions
Journal of Analytical Chemistry, 2005Some hypotheses are discussed for the nature of “inhibited” or “kinetically hindered” redox reactions, which are employed as indicator reactions in kinetic analytical methods. Some reactions are considered as examples to demonstrate that redox reactions are kinetically hindered because the key frontier orbitals of the reagents differ in their symmetry ...

Fresenius' Zeitschrift für analytische Chemie, 1967
A rapid titration procedure is recommended for the estimation of Na2S2O4 in commercial sodium dithionite (sodium hydrosulphite, sodium hyposulphite) and in aqueous solutions of this compound, using potassium hexacyanoferrate(III) as reagent and methylene blue as indicator.
