Ytterbium Chloride Anhydrous YbCl3 CAS 10361-91-8 For NMR Shift Reagent
Name: anhydrous ytterbium chloride, ytterbium chloride ultra dry CAS: 10361-91-8
Molecular formula: YbCl3 Molecular weight: 279.40
Description: The valence electron configuration of Yb3 + (from ytterbium chloride) is 4f135s25p6, which is the key to influence the chemical behavior of Yb3 +. The size of Yb3 + also affects its catalytic performance and biological application. Ytterbium chloride can be prepared by reaction of Yb2O3 with carbon tetrachloride or hot hydrochloric acid. There are better methods to prepare ytterbium chloride for experiment. HCl solution / ammonium chloride method is a low-level and effective method. In addition, YbCl3 hydrate can be dehydrated by various reagents, especially trimethylsilane chloride. Other published methods include the reaction of fine metal powder with mercuric chloride at high temperature in a closed tube.

Packing: topical 5kg / bag or 1kg / bag Vacuum packaging, also provided small package: 100g, 200g, 500g aluminum foil bag vacuum small package.
Uses: It has an unpaired f electron, which can be used as Lewis acid to fill 4f orbital domain. Ytterbium chloride is a kind of nuclear magnetic resonance displacement reagent, which makes the nucleus in contact with YbCl3 produce different resonance with the nucleus not in contact with the displacement reagent. YbCl3 can increase the fluorescent agent attached to the target DNA by 50-80 times, which can make a revolutionary breakthrough in infectious disease detection.
