Product Name:4-Chloro-2-fluoro-5-nitrobenzaldehyde
English Name:4-Chloro-2-fluoro-5-nitrobenzaldehyde
CAS No.:1639298-89-7
Aliases:2-Fluoro-4-chloro-5-nitrobenzaldehyde, Benzaldehyde, 4-chloro-2-fluoro-5-nitro-
Molecular Formula:C7H3ClFNO3
Physical Properties:Pale yellow to yellow crystalline powder. Melting point 85-89°C; atmospheric boiling point approximately 305°C (with partial decomposition); flash point approximately 145°C; relative density approximately 1.56. Freely soluble in organic solvents such as dichloromethane, ethyl acetate, ethanol, acetone and DMF; sparingly soluble in water. Store in a sealed, light-protected, cool and dry place.
Uses:This product is an important fluorine-containing fine chemical intermediate mainly used in the synthesis of pharmaceuticals and agrochemicals. It can be used to prepare fluorine-containing heterocyclic active molecules such as quinazolines and indoles, and serves as a key starting material for various kinase inhibitors and antibacterial drugs. Through reactions such as nitro reduction, aldehyde transformation and halogen coupling, it can be further converted into herbicides, insecticides and functional materials.
Technical Specifications:
Appearance: pale yellow to yellow crystalline powder.
Purity (HPLC): ≥98%.
Molecular weight: 203.55.
Melting point: 85-89°C.
Packaging: 10 kg/bag.
