Product Name:UV Absorber 571
English Name:UV Absorber 571
CAS No.:23328-53-2
Aliases:UV-571, 2-(2H-benzotriazol-2-yl)-6-dodecyl-4-methylphenol
Molecular Formula:C25H35N3O
Physical Properties:Slightly yellow viscous liquid with a mild characteristic odor. Relative density is approximately 1.0-1.1. Insoluble in water, soluble in common organic solvents such as toluene, xylene, and ethyl acetate. It effectively absorbs UV radiation in the 300-400 nm range and exhibits excellent light stability.
Uses:Used as a high-efficiency UV absorber for polymers such as polyurethane, acrylic resins, and polyvinyl chloride. It effectively inhibits yellowing and degradation caused by UV light, extending the service life of end products.
Technical Specifications:
Appearance: slightly yellow viscous liquid
Assay (HPLC): ≥98%
Relative density (20°C): 1.0-1.1
Water content: ≤0.1%
Solubility (25°C, in toluene): ≥50g/100mL
