English description（英文原文，共 1240 字符）
Product Name:4-Hydroxy TEMPO Benzoate
English Name:4-Hydroxy TEMPO Benzoate
CAS No.:3225-26-1
Aliases:4HTBA, 4-Benzoyloxy-2,2,6,6-tetramethylpiperidine-1-oxyl
Molecular Formula:C16H22NO3
Physical Properties:Pale yellow to orange crystalline powder with antioxidant activity and free radical stability. Insoluble in water, readily soluble in chloroform, dichloromethane, ethanol, ethyl acetate and other organic solvents. Slowly decomposes upon exposure to light, heat or oxidizing agents; should be sealed and stored away from light.
Uses:This product serves as a key intermediate for hindered amine light stabilizers (HALS) and is widely applied in the anti-photoaging and anti-thermal-oxidative degradation of polymer materials. It also acts as a nitroxide radical catalyst for the selective catalytic oxidation of alcohols. In organic synthesis, it is employed as a free radical scavenger and polymerization inhibitor for precise control of polymer molecular weight and structure.
Technical Specifications:
Purity ≥ 98% (HPLC)
Appearance: pale yellow to orange crystalline powder
Melting point range: 86–89°C
Packaging: 25kg/cardboard drum, 50kg/plastic drum
Storage: sealed, protected from light, stored in a dry, cool place
