Uses
- Dye and pigment industry: used to synthesize anthraquinone dyes (such as vat dyes and acid dyes), giving textiles, leather and other products lasting colors and light resistance.
- Organic synthesis intermediates: can be used to synthesize derivatives such as anthraquinone and anthracene carboxylic acid, or to construct complex aromatic ring compounds (such as polycyclic aromatic hydrocarbons and fluorescent dye intermediates) through condensation reactions.
- Material science: 9-Anthraldehyde is used as a raw material to prepare anthracene-based luminescent materials for organic light-emitting diodes (OLEDs), fluorescent probes or photovoltaic materials. The introduction of anthracene aldehyde structure improves the optical or thermal stability of polymers and is used in special plastics or coatings.
- Medicine and biochemistry: Some anthracene compounds have anti-tumor activity, and 9-Anthraldehyde can be used as an intermediate for the synthesis of anthraquinone anticancer drugs. Its fluorescence properties can also be used to develop biomolecular detection reagents (such as cell imaging probes).
- Research and analysis: used as a standard or reagent for organic reaction mechanism research and qualitative and quantitative detection of chromatographic analysis.
Safety Information
9-Anthraldehyde is irritating to a certain extent. If it comes into contact with the skin or eyes, it should be rinsed with clean water in time. During the operation, personal protective equipment such as protective gloves and protective glasses should be worn to avoid inhalation or contact.
