19423-87-1 Usage
Uses
Used in Chemical Synthesis:
Ytterbium(III) chloride hydrate is used as an effective catalyst for preparing acetals by reacting with trimethyl orthoformate. It also reacts with N-alkylsalicylideneimines to prepare yttrium(III) Schiff base complexes.
Used in Analytical Chemistry:
Ytterbium(III) chloride hydrate is widely used as an NMR shift reagent, calcium ion probe, and in DNA microarrays, making it a valuable tool in analytical chemistry.
Used in Organic Chemistry:
The anhydrous form of ytterbium(III) chloride hydrate acts as a Lewis acid and catalyzes various alkylation reactions, such as the aldol reaction and Pictet-Spengler reaction, making it a useful catalyst in organic chemistry.
Used in Glass Coloring:
Ytterbium(III) chloride hydrate has applications in glass coloring due to the narrow absorption band of the erbium ion, which colors erbium salts pink. It is used in eyeware and decorative glassware and can neutralize discoloring impurities such as ferric ions to produce a neutral gray shade.
Used in Fiber Optics and Lasers:
Erbium, which is closely related to ytterbium, has applications in fiber optics as an amplifier and in lasers for medical and dental use. Lasers based on Er:YAG are ideally suited for surgical applications due to their ability to deliver energy without thermal build-up in tissue.
Used in Metallurgy:
Erbium, a related element, is used as a metallurgical additive. When added to vanadium, for example, erbium lowers hardness and improves workability. It also has applications in neutron-absorbing control rods for nuclear reactors, cubic zirconia, and porcelain, and cryocoolers.
Check Digit Verification of cas no
The CAS Registry Mumber 19423-87-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,2 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19423-87:
(7*1)+(6*9)+(5*4)+(4*2)+(3*3)+(2*8)+(1*7)=121
121 % 10 = 1
So 19423-87-1 is a valid CAS Registry Number.
