Description and Uses
                                            Isatin can be used as a reactant to prepare:
- Phthalazinone derivatives.
 - Spirooxindole derivatives.
 - Agents against multidrug-resistant cells expressing P-glycoprotein.
 - Thiazolidinones spiro-fused to indolin-2-ones as potent and selective inhibitors of Mycobacterium tuberculosis protein tyrosine phosphatase B.
 - Triazole-isatine compounds as potential antibacterial and antifungal agents.
 - Biologically relevant scaffolds such as spiro[indole-thiazolidinones].
 
It can be a reactant for:
- Cascade reactions with heterocyclic ketene aminals.
 - Knoevenagel condensation reactions.
 
Isatin can also be used as a chromatographic spray reagent for amino acids, and also as a reference material in the preparation of indigo and Maya Blue. It is responsible for the yellow color exhibited by the "Maya Yellow" pigment.
