1. the product is used as an intermediate in dyestuff and medicine. It is used to produce drug Xin Kefen and disperse yellow E-3G. In chemical analysis, it is a reagent for the determination of copper ion, thiol, thiophene and urinary blue mother.
2. for reducing dyes and drugs and so on
3. as a reagent for the determination of ketone and thiophene
4. indigo and Mayan blue are used as reference material to prepare indigo and Mayan blue; it is used to prepare two azoacetone derivatives, spironolyl indole derivatives and P- glycoproteins for multidrug resistant cells. Thiazole -4- ketone is fused into indole 2- ketone through a spiral ring. As a protein tyrosine phosphatase B of Mycobacterium tuberculosis, it is a powerful choice. Selective inhibitors, three azoles Isatine complexes as strong antibacterial agents and antifungal agents, biological activity related structures such as the stud (indolothiazole -4- ketone); used in series with heterocyclic acetal amines and Knoevenagel enrichment; indigo using direct sp2/sp3C-H bond activation reaction, Pd (II) The C-H addition reaction forms 3- to replace -3- hydroxyl 2- hydroxyindole.
5. to test the precipitant of ketone and silver. Spectrophotometric Determination of thiophene, thiol, thiophene, urine rum and proline reagent.
