Disulfidodicarbamidine, also known as DSD, is a chemical compound with the formula (NH2)2CS2. It is a colorless, crystalline solid that is soluble in water and has a melting point of approximately 90°C. DSD is primarily used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. It is also known for its ability to form disulfide bonds, which are crucial in the formation of proteins and other biological molecules. The compound is produced industrially through the reaction of carbon disulfide with ammonia and is considered a hazardous material due to its potential to cause respiratory and skin irritation.

3256-06-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3256-06-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,5 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3256-06:
(6*3)+(5*2)+(4*5)+(3*6)+(2*0)+(1*6)=72
72 % 10 = 2
So 3256-06-2 is a valid CAS Registry Number.

Selective oxidation of thiourea with H2O2 catalyzed by [RuIII(edta)(H2O)]-: Kinetic and mechanistic studies

Chatterjee, Debabrata,Rothbart, Sabine,Van Eldik, Rudi

, p. 4725 - 4729 (2013/05/09)

Reported here is the first example of a ruthenium complex, [Ru III(edta)(H2O)]- (edta4- = ethylenediaminetetraacetate), that catalyzes the oxidation of thiourea (TU) in the presence of H2O2. The kinetics and mechanism of this reaction were investigated in detail by using rapid-scan spectrophotometry as a function of both the hydrogen peroxide and thiourea concentrations at pH 4.9 and 25 °C. Spectral analyses and kinetic data clearly support a catalytic process in which hydrogen peroxide reacts directly with thiourea coordinated to the RuIII(edta) complex. HPLC product analyses revealed the formation of formamidine disulfide (TU2) as a major product at the end of the catalytic process, however, formation of other products like thiourea dioxide (TUO2), thiourea dioxide (TUO3) and sulfate was also observed after longer reaction times. Catalytic intermediates such as [Ru III(edta)(OOH)]2- and [RuV(edta)(O)] - were evidently found to be non-reactive in catalyzing the oxidation of thiourea by H2O2 under the specified conditions.
