51116-03-1 Usage

General Description

2,3-Dibromo-1-propanesulfonic acid sodium salt is a chemical compound with the formula C3H4Br2O3SNa. It is a water-soluble, white to off-white crystalline powder that is primarily used as a reagent in organic synthesis and as an intermediate in the production of pharmaceuticals, agrochemicals, and other fine chemicals. It is a strong sulfonic acid that can be used as a catalyst in various chemical reactions and as a stabilizer in certain polymers. Additionally, it is used as a dye intermediate and in the manufacture of surfactants and emulsifying agents. Due to its ability to react with a wide range of organic compounds, it is a versatile and important chemical in the field of organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 51116-03-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,1,1 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 51116-03:
(7*5)+(6*1)+(5*1)+(4*1)+(3*6)+(2*0)+(1*3)=71
71 % 10 = 1
So 51116-03-1 is a valid CAS Registry Number.

Method for preparing sodium 2,3-dimercapto-1-propanesulfonate

-

Paragraph 0038; 0039; 0040; 0041; 0042, (2019/05/08)

The invention belongs to the technical field of drug synthesis, and in particular relates to a method for preparing sodium 2,3-dimercapto-1-propanesulfonate. With sodium allysulfonate used as a starting material and through a bromination reaction, a sulfhydrylation reaction, a lead salt reaction and a lead removal reaction, high-content sodium 2,3-dimercapto-1-propanesulfonate is obtained by refinement. The total yield is 23.2% and above; especially when zinc dust reduction step is added after hydrolysis, the yield can be greatly increased, the total yield can reach 35-41.5%, and the refined sodium 2,3-dimercapto-1-propanesulfonate content reaches 99% and above. Ethanethioic acid potassium salt is used as a sulphurizing agent and then is hydrolyzed under strong acid conditions, and dilutesulfuric acid is used for lead removal after lead formation. During the whole reaction and treatment process, toxic gas hydrogen sulfide which affects the environment is prevented from being used or generated. Thereby, working conditions are improved, emission of three wastes is reduced, and production efficiency is enhanced.

1,3-Dipolar cycloaddition reactions of nitrones to prop-1-ene-1,3-sultone

, p. 1329 - 1334 (2007/10/03)

The reaction of prop-1-ene-1,3-sultone (1) with a variety of nitrones 2 afforded novel [3+2] cycloaddition products 3, 4, and 5 in good yield. Excellent regio- and stereoselectivity were achieved in the cycloaddition reaction with phenylnitrones.

Synthesis and Diels-Alder reactions of prop-1-ene-1,3-sultone, and chemical transformations of the Diels-Alder adducts

Jiang, La Sheng,Chan, Wing Hong,Lee, Albert W. M.

, p. 2245 - 2262 (2007/10/03)

A reliable and novel synthetic route for the preparation of prop-1-ene- 1,3-sultone (1) has been developed. An overall yield of 34% could be achieved for this five-step synthesis. The Diels-Alder reactions of 1 with a variety of dienes were investigated for the first time and achieved with good chemical yield and excellent endo-selectivity. The subsequent transformations of the Diels-Alder cycloadducts were also explored.
