557794-38-4 Usage

Uses

Different sources of media describe the Uses of 557794-38-4 differently. You can refer to the following data:
1. Isotopically labelled Dapsone.A representative lot is 73% d8, 23% d7 and 3% d6 with no d0.
2. Isotopically labelled Dapsone. A representative lot is 73% d8, 23% d7 and 3% d6 with no d0

Check Digit Verification of cas no

The CAS Registry Mumber 557794-38-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,7,9 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 557794-38:
(8*5)+(7*5)+(6*7)+(5*7)+(4*9)+(3*4)+(2*3)+(1*8)=214
214 % 10 = 4
So 557794-38-4 is a valid CAS Registry Number.

A stable isotope labeling dapsone synthetic method

-

Paragraph 0189; 0195; 0196, (2017/04/19)

The invention relates to a synthetic method of stable isotope labeled aminophenylsulfone. The method comprises the following steps: by taking stable isotope labeled p-nitro halogeno benzene as a raw material, carrying out nucleophilic substitution to generate stable isotope labeled 4, 4'-dinitro phenyl sulfide; oxidizing to obtain stable isotope labeled 4, 4'-dinitro diphenyl sulfone; and finally carrying out reaction with a reducing agent to obtain the stable isotope labeled aminophenylsulfone. Compared with the prior art, according to the stable isotope labeled aminophenylsulfone prepared by the invention simply separated and purified, the chemical purity reaches over 99% and the isotope abundance is 99%, so that the demand of aminophenylsulfone detection of forbidden sulfonamides in the field of food safety can be fully satisfied.
