What is 4-Fluorobenzaldehyde CAS 459-57-4?
Molecular formula: C₇H₅FO, molecular weight 124.11 g/mol.
Physical property parameters
Appearance: Colorless to pale yellow transparent liquid with a bitter almond flavor and strong refractive properties.
Boiling point: 181°C (758 mmHg), melting point: -10°C, flash point: 56°C (flammable liquid).
Solubility: Slightly soluble in water (0.35g /L), readily soluble in organic solvents such as ethanol, ether and benzene.
Stability: It is prone to oxidation to p-fluorobenzoic acid. It should be stored in a sealed container away from light and avoid contact with oxidants.
Safety risk
Toxicity: Moderate toxicity. Skin contact may cause irritation. Inhalation of vapor may cause respiratory tract damage.
Operation protection: Chemical protective gloves, goggles and gas masks are required. Operations should be conducted in a fume hood.
Storage: Cool and dry place (≤25℃), away from fire sources, transport as hazardous chemicals (UN 3446, PG II).
