5-hydroxy-7-azaindole (CAS:98549-88-3) is an important pyridine derivatives, which is widely used in various of chemical fields.

Its main applications are as follows:

1. 5-hydroxy-7-azaindole serves as a key pharmaceutical intermediate for synthesizing kinase inhibitors and anti-inflammatory small molecule drugs.
2. 5-hydroxy-7-azaindole is applied to prepare water-soluble fluorescent probes used in biological cell labeling and biochemical detection.
3. 5-hydroxy-7-azaindole acts as a building block for synthesizing organic optoelectronic materials and organic luminescent functional derivatives.

1. Store 5-hydroxy-7-azaindole in lightproof sealed containers below 25°C under dry ventilated conditions to prevent phenolic hydroxyl oxidation and discoloration.
2. Avoid frequent opening of 5-hydroxy-7-azaindole packages to stop moisture absorption and caking of solid powder.
3. Store 5-hydroxy-7-azaindole separately from strong oxidants and strong alkalis to prevent irreversible structural damage of the heterocyclic framework.

1. The phenolic hydroxyl group of 5-hydroxy-7-azaindole can undergo etherification, esterification and electrophilic substitution to achieve diversified molecular modification.
2. The rigid fused ring structure of 5-hydroxy-7-azaindole possesses good molecular affinity with biological target proteins for drug molecular design.
3. 5-hydroxy-7-azaindole has stable reaction activity in mild reaction systems and effectively reduces the generation of miscellaneous by-products.

1. Refuse inhalation of dust of 5-hydroxy-7-azaindole; wear dust masks, splash-proof goggles and nitrile gloves during weighing and transferring operations.
2. 5-hydroxy-7-azaindole causes mild irritation to skin, eyes and respiratory mucosa; flush contaminated areas with plenty of running water for no less than 15 minutes after contact.
3. Waste solids and waste solvents containing 5-hydroxy-7-azaindole need to be disposed in accordance with hazardous waste management standards for hydroxyl azaindole compounds.
