Potassium 2,3,3-trimethylindole-5-sulfonate
Potassium 2,3,3-trimethylindole-5-sulfonate (2,3,3-Trimethylindolenine-5-sulfonic acid potassium salt) is an indole derivative containing a sodium sulfonate group and is commonly used as a key intermediate in dye synthesis. Potassium 2,3,3-trimethylindole-5-sulfonate can be coupled to peptides, proteins, nucleic acids, RNA, DNA, carbohydrates, polymers, and small molecules via the sulfonyl substituent[1].
