Conventional methods to determine esterase activity from insects are composed of a three-step process where the enzyme is allowed to hydrolyze a 1-naphthyl acetate substrate, that reaction is quenched by a SDS detergent, and then a Fast Blue B dye complex is formed with 1-naphthol, the product of 1-naphthyl acetate hydrolysis.

18960033 Betteridge D: Extractive indicators in complex-formation titrations: theory and practice. Talanta. 1966 Nov;13(11):1497-516.

The use of conditional constants to predict the optimum conditions for titration in several complex-formation titrations, in which the end-point is detected by the formation of a coloured extractable complex, is demonstrated.
The predictions have been tested by experiment. 2-(2-Pyridylazo)-1-naphthol is shown to be a useful extractive indicator for the copper-EDTA titration; dimethylglyoxine is not recommended as an extractive indicator for the nickel-EDTA titration; the titration of fluoride with aluminium, using 8-hydroxy-quinoline as an extractive indicator, is shown to be undesirable theoretically and experimentally.
