Belkhim OJSC offers phenolphthalein and other chemical indicators: bengale red, dimethyl yellow, dithizone, cupferron, malachite green, methylene blue, methyl red and orange, pyrogallol, chrome dark blue, erychrome black. Introduction of chemical indicators into the test solution allows for establishing chemical reaction end point or pH of the solution by easily remarkable sign (discoloration, turbidity appearance or disappearance, luminescence, etc.). Chemical indicators are primarily used in titrimetric analysis for establishing equivalence point (titration end point).

Malachite green (benzal green) is widely used as follows:
- for indirect determination of P, W, sulphites, as a reagent in microbiology,
- in microscopy for intravital staining of cell nucleuses,
- for staining erythrocytes, ascarid eggs,
- as a drug product, in particular, during treatment of aquarium fish from infectious diseases, etc.
