Application Areas
Organic Synthesis and Medicinal Chemistry
As a derivative of azulene, it may be used to synthesize drug molecules with anti-inflammatory, antioxidant, or antibacterial activities.
As an intermediate in photosensitive materials or dye chemistry, it is used to develop new functional materials.
material science
May be used in the research of organic semiconductors, fluorescent probes, or optoelectronic materials, as their conjugated structures may possess special optoelectronic properties.
Storage conditions
Environmental conditions: Store at -20 ° C to 4 ° C (refrigerated or frozen), away from light (wrapped in brown glass bottles or aluminum foil), to prevent photolysis or oxidation. Long term storage is recommended to seal with an inert gas (such as nitrogen or argon).
Container selection: Use glass bottles with good sealing properties (to prevent impurities from dissolving out of plastic containers), lined with polytetrafluoroethylene (PTFE) gaskets.
Stability precautions: prone to oxidation or photodegradation, regular purity and decomposition checks are necessary.
Safety precautions
Health hazards: May be irritating to the skin and eyes, protective gloves and goggles should be worn during operation.
Leakage treatment: Small leaks can be adsorbed with inert materials, while large leaks need to be isolated in contaminated areas and professionally disposed of.
Explosion risk: There is no clear explosion report, but it is necessary to stay away from open flames and strong oxidants
