Physicochemical parameters
Melting point: 114-120°C
Boiling point: 264°C
Solubility: Readily soluble in water (263 g/L), methanol; Slightly soluble in chloroform and carbon disulfide.
Stability: It should be stored in a dark and sealed container. Long-term exposure to air may cause oxidation and discoloration.
Spectral and computational data
Hydrogen bond donor/acceptor: 2/2
Topological polar surface area: 40.5 A ²
Hydrophobic parameter (XlogP) : 1.6, indicating moderate lipophilicity.
Organic synthesis intermediates
In the medical field: Synthesis of psoralen derivatives (such as 4,5', 8-trimethylpsoralen) for the treatment of skin diseases.
Functional material: As a phenolic resin modifier, it enhances the water resistance of adhesives (such as wood and tire cord bonding).
Industrial and scientific research applications
Dye synthesis: Preparation of azo dyes and fluorescent markers.
Analytical reagents: Used for colorimetric detection of metal ions (such as zinc and lead).
Classification of hazards
Toxicity: Toxic upon ingestion (LD₅₀ rats oral: 301 mg/kg), irritating eyes, skin and respiratory tract.
Hazard Signs
R25 (Toxic if swallowed)
R36/37/38 (Irritating eyes/respiratory tract/skin)
UN 2811 (Class 6.1 Dangerous Goods)
Carcinogenicity: The IARC has not clearly classified it, but long-term exposure should be avoided.
Operation protection
Essential equipment: Gas mask, chemical protective suit, acid-resistant gloves and goggles (safety terms: S26/S36/S37/39).
Leakage treatment: Absorb with sand and avoid direct contact with skin. A large amount of leakage requires professional hazardous waste disposal.
Storage requirements
Seal and keep away from light. Cool and dry (≤25℃), away from oxidants and strong acids.
