General Description

The chemical substance represented by the molecular formula "C21H23F5NO5P" is a complex organic compound. It is composed of 21 carbon (C) atoms, 23 hydrogen (H) atoms, 5 fluorine (F) atoms, 1 nitrogen (N) atom, 5 oxygen (O) atoms and 1 phosphorus (P) atom. The specific characteristics of the compound, including its density, boiling and melting points, as well as its physical and chemical properties, depend on the specific arrangement of these atoms. It could potentially be used in a wide array of fields such as medicine, chemistry, and materials science, depending on its properties. However, without a specific name or structural information, it's hard to provide more detail about this compound.

Check Digit Verification of cas no

The CAS Registry Mumber 1911578-98-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,9,1,1,5,7 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1911578-98:
(9*1)+(8*9)+(7*1)+(6*1)+(5*5)+(4*7)+(3*8)+(2*9)+(1*8)=197
197 % 10 = 7
So 1911578-98-7 is a valid CAS Registry Number.

Dynamic kinetic resolution method for tail chain of Remdesivir phosphoric acid intermediate

-

Paragraph 0049-0052, (2021/09/21)

The invention relates to a drug intermediate of an RNA polymerase inhibitor, in particular to an intermediate of Remdesivir phosphate and a preparation method of the intermediate. According to the method, a compound Sp/Rp epimerization mixture in a formula (I) is crystallized under a dynamic kinetic resolution condition, so that the Rp single configuration isomer, in a formula (I'), of the Remdesivir intermediate is obtained. In the synthesis process, an epimerization mixture of the compound shown in the formula (I) is finally converted into a single-configuration I'compound through crystallization-induced epimerization under the dynamic kinetic resolution condition, so that the total yield of the reaction is increased, the utilization rate of raw materials is increased, and the process is more environmentally friendly and efficient.

Ribavirin side chain intermediate and preparation method thereof (by machine translation)

-

Paragraph 0047-0057, (2020/07/02)

To the method, the intermediate state is obtained by reaction of phenyl diphenyl phosphate and pentafluorophenol in an organic solvent under basic conditions, and an alanine (2 - ethyl butyl) ester hydrochloride is added to carry out butt-joint reaction, and then an organic solvent is used for refining to obtain high-purity target product N - [(S) (2,n-alanine) - L L-alanine (2 - ethylbutyl) ester. The method has great help for the current severe novel coronavirus 2019 - nCoV (?datdatdatas) epidemic situation control work. (by machine translation)
