Product Name:4-Amino-2,3-difluoro-5-nitrobenzoic acid
English Name:4-Amino-2,3-difluoro-5-nitrobenzoic acid
CAS No.:284030-57-5
Aliases:4-Amino-2,3-difluoro-5-nitrobenzoic acid, 2,3-Difluoro-4-amino-5-nitrobenzoic acid
Molecular Formula:C7H4F2N2O4
Physical Properties:Off-white to light yellow crystalline powder. Molecular weight 218.11, density approximately 1.7 g/cm³ (predicted), melting point approximately 200°C (decomposes), boiling point approximately 380°C (predicted). Slightly soluble in water, soluble in methanol, ethanol, dimethylformamide and other organic solvents. Exhibits typical reactivity of aromatic nitro compounds and aminobenzoic acids; light- and heat-sensitive; store in a cool, dry place away from light and airtight.
Uses:This product is a fluorinated benzoic acid derivative and serves as an important intermediate in the synthesis of pharmaceuticals, agrochemicals, and fine chemicals. It is commonly used to prepare fluoroquinolone antibacterial agents and antitumor drug molecules, introducing fluorine atoms and aminocarboxylic acid fragments to enhance biological activity. It can also be employed as a building block for functional molecules in materials science.
Technical Specifications:
Appearance: off-white to light yellow crystalline powder
Assay (HPLC): ≥98.0%
Melting point: approximately 200°C (decomposes)
Water content: ≤0.5%
