If the eyes and skin are touched, they should be immediately rinsed with plenty of flowing water. The working environment should be well ventilated. Mixing with oxidant and edible chemicals is strictly prohibited.
toxic substance data | 148-18-5(Hazardous Substances Data) |
Solubility | about 35 % in water, less soluble in organic solvents. However, the free acid, diethyldithiocarbamic acid, is readily soluble in organic solvents and less soluble in water. Thus, on acidification of an aqueous solution of a diethyldithiocarbamate, the free acid can be extracted with chloroform or carbon tetrachloride. The distribution ratio is 2,360 for chloroform and 343 for carbon tetrachloride. |

application
Copper reagent is used in the color reaction of copper, used as a precipitant and solvent extractant for soft metal ions, and also used as a photometric reagent for the determination of metals such as bismuth, copper, and nickel.
Test example
Applicability test for copper
measure 1.0 mL of sample solution (4.3.1) after water dissolution test and dilute to 10mL.
measure 1.0 mL of copper impurity standard solution (1 mL of Luo solution contains 0.001 mgCu), place it in a separatory funnel, add 0.5 mL of ammonia solution (10%), and dilute it to 20mL. Add 1.0 mL of the diluted sample volume and 5.0 mL of isoamyl alcohol, shake for 1min, and place. At the same time, a blank test was made. The organic layer should be yellow, which is obviously different from the blank test solution.
Determination of impurities
the sample must be weighed to 0.01g.
1 water dissolution test
weigh 0.5g of sample and put it in 25mL of water. the liquid volume should be clear and free of mechanical impurities (the liquid volume of this sample should be retained for determination of copper applicability test).
2 burn residue
weigh 1 g of sample, place it in the ground light with constant weight at 650±50 ℃, slowly heat it until carbonization and cooling, moisten the residue with 1mL sulfuric acid, continue heating until sulfuric acid vapor escapes, and burn it to constant weight in a high temperature furnace at 650±50 ℃.
The residue content is calculated according to the following formula:
x =m1/m×100
formula: x-percentage content of residue,%;
m1 mass of residue after burning, g;
m-sample mass, g.
biological activity
Ditiocarb sodium (Sodium diethyldithiocarbamate) is a copper reagent, which reacts with Cu2 + solution to form a complex, which improves the precipitation rate of copper replacement. Sodium diethyldithiocarbamate can reduce HIV infection.
Target
HIV
in vitro studies
Ditiocarb sodium (Sodium diethyldithiocarbamate) reacts with the Cu 2+ solution giving a complex of copper diethyldithiocarbamate, which enhances the rate of cementation. Ditiocarb sodium is an agent with strong antioxidant capacity and chelating activities.
In vivo studies
Ditiocarb sodium (Sodium diethyldithiocarbamate) improves the depressed immune responses of newborn and aged mice. Sodium diethyldithiocarbamate prevents cisplatin nephrotoxicity in animals without reducing the antitumor activity. In that AIDS model, Ditiocarb sodium reduces lymphadenopathy and hypergammaglobulinemia, restores immunocompetence, and prolongs survival.
