主要成分 Main Component |
烟酸甲酯(Methyl Nicotinate)是烟酸(维生素 B3/尼克酸)的甲酯,化学名甲基吡啶-3-羧酸酯,分子式 C7H7NO2;由烟酸经酯化制得,常温下为白色至褐色晶体或结晶粉末,熔点约 42–44 °C,溶于乙醇、苯等有机溶剂及水(约 0.1 g/mL)。其主要药理特性为外用皮肤血管扩张(发红),广泛用作化妆品(唇蜜、丰唇)与医药(发红剂、兽医透皮制剂)原料,亦作香精香料(FEMA 3709)。 Methyl nicotinate is the methyl ester of niacin (vit. B3/nicotinic acid), IUPAC methyl pyridine-3-carboxylate, C7H7NO2; produced by esterification of niacin; white to brownish crystals/powder, mp ~42–44 °C, soluble in ethanol/benzene and water (~0.1 g/mL). Its key property is topical vasodilation (rubefaction), used in cosmetics (lip plumper), pharma (rubefacient, veterinary), and as flavor/fragrance (FEMA 3709). |
