Product Description

Potassium 2,3,3-trimethyl-3H-indole-5-sulfonate CAS 184351-56-2 Water-soluble Heterocyclic

Product Overview

Potassium 2,3,3-trimethyl-3H-indole-5-sulfonate is an indole derivative with stable sulfonate structure. It presents good solubility in polar organic solvents and aqueous systems. The substance supports coupling reactions and acts as a foundational building block for cyanine fluorescent dyes, widely adopted within biochemical labeling research. It requires proper light-proof and low-temperature preservation to maintain structural stability.

Chemical Properties

This heterocyclic sulfonate salt features an indolenine parent skeleton. The sulfonate group brings improved hydrophilicity compared with non-sulfonated indole compounds. It remains stable under normal anhydrous conditions yet sensitive to prolonged strong illumination and high humidity. The molecular structure can participate in condensation reactions to construct near-infrared fluorescent dye skeletons.

Applications

Raw material for synthesis of cyanine fluorescent dyes
Biochemical labeling intermediate targeting protein, nucleic acid conjugation
Research material for optical biomarker development
Organic synthesis building block for heterocyclic functional compounds

Q: How should this product be stored for long-term use?

A: Keep tightly sealed under low temperature, shielded from light and humid air to prevent degradation.

Q: Which solvents are suitable for sample preparation?

A: DMSO, DMF and purified water are common solvent options.

Q: Can this material be directly applied to biological experiments?

A: It serves as synthetic intermediate, further chemical modification is generally required before labeling tests.
