说明

General description

氯化锌（ZnCl₂）是一种无机化合物，在化学合成中常用作试剂。它在环加成、取代、亲电芳香加成和选择性还原反应中用作温和的路易斯酸催化剂。ZnCl₂ 也是通过转金属反应合成许多有机锌试剂的有用原料。

Application

氯化锌可用作：

催化剂，通过有机腈与叠氮化钠的[3 + 2]环加成反应合成 5-取代 1H-四唑。
试剂，促进 NaBH₄ 水解以生成氢。
试剂，活化碳材料。

Redi-Dri™ – The World of Free-flowing Hygroscopic Products

Redi-Dri™ prevents hygroscopic powders, such as inorganic salts, from absorbing moisture and forming clumps, leaving the salts free-flowing every time.

Transferrin 1 Functions in Iron Trafficking and Genetically Interacts with Ferritin in Drosophila melanogaster.

Guiran Xiao et al.

Cell reports, 26(3), 748-758 (2019-01-17)

Iron metabolism is an essential process that when dysregulated causes disease. Mammalian serum transferrin (TF) plays a primary role in delivering iron to cells. To improve our understanding of the conservation of iron metabolism between species, we investigate here the

Local ZnCl2 accelerates fracture healing.

Aaron Wey et al.

Journal of orthopaedic research : official publication of the Orthopaedic Research Society, 32(6), 834-841 (2014-02-28)

This study evaluated the effect of local zinc chloride (ZnCl2 ), an insulin mimetic agent, upon the early and late parameters of fracture healing in rats using a standard femur fracture model. Mechanical testing, radiographic scoring, histomorphometry, qualitative histological scoring
