用途: 4-Methylumbelliferyl palmitate is an excellent fluorophore for measuring acid lipase in human leukocytes. Acidity and solvent have important influence on its fluorescence. 4-Methylumbelliferyl palmitate exists mainly as neutral molecular form which can be produced strong fluorescence at 445 nm in near neutral aqueous solutions, and exist mainly as anion form which can be produced stronger fluorescence at 445 nm in weak alkaline solutions[1][2]. 物理化学性质: CAS号:17695-48-6 常用中文名:4-甲基伞形基棕榈酸酯 常用英文名:4-Methyl-2-oxo-2H-chromen-7-yl palmitate 分子式:C26H38O4 分子量:414.578 密度:1.0±0.1 g/cm3 沸点:535.2±45.0 °C at 760 mmHg 熔点:77ºC(lit.) 闪点:261.8±27.1 °C |
