Indole-5-carboxaldehyde CAS 1196-69-6

Indole-5-carboxaldehyde (CAS:1196-69-6) is an important Indole compounds.

Its main applications including:

1. Fundamental indole building block for antitumor and central nervous system drug research and synthesis.
2. Indole-5-carboxaldehyde is widely used substrate for Knoevenagel condensation, cross-coupling and multi-step heterocycle construction.
3. Indole-5-carboxaldehyde is a raw material for fluorescent biological probes and nitrogen-containing organic optoelectronic materials.

1. Seal tightly and store below 25°C in dry dark warehouse to prevent photooxidation of aldehyde and indole skeleton.
2. Minimize repeated opening of packages to avoid oxidation, discoloration and self-polymerization.
3. Store separately from amines, strong oxidants, strong alkalis and nucleophilic reagents.

1. Avoid inhalation of crystalline dust; wear dust mask and chemical-resistant gloves during weighing and handling.
2. Never ingest the solid; flush contaminated eyes and skin with abundant running water immediately.
3. Dispose waste residues and filtrate according to nitrogen-containing aromatic aldehyde hazardous waste regulations.

1. Reactive aldehyde group supports condensation, reduction and reductive amination derivatization reactions.
2. Indole heterocyclic framework remains stable under conventional mild synthetic reaction conditions.
3. High crystalline purity helps obtain consistent yields in the preparation of bioactive heterocyclic intermediates.
