Foursulfonic acidsodiuMhydrate,two - Reference Information
| application | sodium tetrasulfate is widely used in the process of biomedicine as a mutating agent for recombinant proteins. |
| preparation | a method for catalyzed synthesis of sodium tetrasulfate with elemental iodine. the specific steps are as follows: sodium thiosulfate, water, elemental iodine and organic solvent a are sequentially added to the reactor to react for 4-36h at 0-40 ℃. after the reaction is completed, the filter cake is dissolved in water and filtered, add the filtrate to the cold organic solvent B for recrystallization, filter, and dry to obtain the product with sodium tetrasfate. The specific steps are as follows: 1) Weigh and add activated carbon dried to constant weight into 2.5% iodine ethanol solution, stir at room temperature and filter, rinse with ethanol to neutral many times, dry to constant weight at 70 ℃, put into a dryer, cool and weigh, and calculate the load. That is, iodine loading =(W1-W)/W1 × 100%, where W1 is the mass (g) of activated carbon after loading and W is the mass (g) of activated carbon before loading. 2) Add 20g of sodium thiosulfate pentahydrate and 20ml of water to a 500ml eggplant-shaped bottle, stir until dissolved at 4 ℃, then add 35g of iodine prepared by the method described in Example 1 to the eggplant-shaped bottle. The loading amount is 30% activated carbon loaded with elemental iodine, 100ml of anhydrous ethanol, stir for 12 hours at 4 ℃, filter, wash the filter cake three times with 10ml of anhydrous ethanol, place the filter cake in a 100ml beaker, add 10ml of water, stir and dissolve, filtering, adding the filtrate to a 500ml eggplant-shaped bottle, adding 100ml of cold anhydrous ethanol to it, stirring for 6 hours, filtering, washing the filter cake with 10ml anhydrous ethanol for three times, placing the filter cake in a vacuum drying oven at 2-8 ℃ and drying for 12 hours to obtain the product sodium tetrasulfate. After calculation, the yield is 72% and the purity is 95%. |
| use | quantitative determination of cystine and cysteine in protein. Reversibly modify the cysteine residue of bacterial fluorescein. |
