Uses

Different sources of media describe the Uses of 452339-73-0 differently. You can refer to the following data:
1. (5R)-5-(2,2-diMethyl-4H-1,3-benzodioxin-6-yl)-2-Oxazolidinone is a reagent applied in the preparation of alkyl-linked di-phenyl aminoalcohols as long-acting β2 adrenergic receptor agonist. It is used as an antedrug.
2. R)-5-(2,2-Dimethyl-4H-1,3-benzodioxin-6-yl)-1,3-oxazolidin-2-one is a reagent applied in the preparation of alkyl-linked di-phenyl aminoalcohols as long-acting β2 adrenergic receptor agonist. An antedrug.

Check Digit Verification of cas no

The CAS Registry Mumber 452339-73-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,2,3,3 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 452339-73:
(8*4)+(7*5)+(6*2)+(5*3)+(4*3)+(3*9)+(2*7)+(1*3)=150
150 % 10 = 0
So 452339-73-0 is a valid CAS Registry Number.

Preparation method and application of polyoxometalate crystal

-

Paragraph 0014-0015, (2017/08/31)

The invention belongs to the technical field of organocatalysis and in particular relates to a preparation method and application of a polyoxometalate crystal. The preparation method disclosed by the invention comprises the following steps: by taking Na2WO4.2H2O, NaVO3.2H2O, disodium hydrogen phosphate, manganese acetate and benzyl tri-n-butylammonium chloride as raw materials, preparing the heteropolyacid crystal. Catalyzed preparation of an anti-asthma drug vilanterol trifenatate intermediate is realized by taking the polyoxometalate crystal as a catalyst. The defect in the conventional process that a strong base is adopted is overcome, the pressure for environmental protection is alleviated, the process route is green and environment-friendly, and the requirements on the conventional industrial production are met.
