Indole-4-carboxylic Acid CAS 2124-55-2

Indole-4-carboxylic acid (CAS:2124-55-2) is an important indole derivative.

Its main applications including:

1. Indole-4-carboxylic acid is a key indole building block for anti-tumor and central nervous system small-molecule drug synthesis.
2. Indole-4-carboxylic acid is a raw material for constructing indole-based amide, ester and heterocyclic derivatives via carboxyl modification.
3. Indole-4-carboxylic acid is a precursor for biological fluorescent probes and organic optoelectronic functional materials.

1. Seal tightly and store below 25°C in dry dark warehouse to prevent photooxidation of indole ring.
2. Reduce frequent opening of packages to avoid moisture absorption and oxidative discoloration.
3. Store separately from strong oxidants, strong bases and volatile amine reagents.

1. Avoid inhalation of fine crystalline dust; wear dust mask and chemical-resistant gloves during operation.
2. Do not take orally; flush splashed eyes and skin with large amounts of running water promptly.
3. Treat waste solids and filtrate as nitrogen-containing aromatic hazardous waste for standardized disposal.

1. Carboxyl group enables esterification, amidation and decarboxylation for diversified derivatization.
2. Indole aromatic ring maintains stable structure under mild heating and common catalytic reaction systems.
3. High crystalline purity ensures stable reaction yield for pharmaceutical heterocyclic synthesis.
