描述

产品介绍

易溶于水(可溶解范围约30%)和醇。还原性强,暴露于光线或加热时逐渐变色(变黑)。干燥状态下稳定性强,但在水溶液中遇空气将很快分解。水溶性1g/10mL,,能溶于水、醇和吡啶,颇溶于丙醇,微溶于甘油,其化学性质与抗坏血酸非常相似,具有同样强的还原作用。

别名 D-异抗坏血酸 ;异抗坏血酸; 赤藻糖酸; 异维生素 C; D-2,3,5,6-四羟基-2-己烯酸-gamma-内酯;D-erythro-Hex-2-enoic acid γ-lactone D-Araboascorbic acid D-Erythorbic Acid
应用 异抗坏血酸是维生素C的一种最重要的异构体。
