α,α-Dithiobisformamidinium dinitrate, also known as DTFDN, is a chemical compound with the molecular formula C4H8N4S2?2NO3. It is a white crystalline solid that is soluble in water and serves as a reagent for the determination of metal ions, particularly copper, silver, and mercury. The compound forms colored complexes with these metal ions, which can be used for their detection and quantification. DTFDN is also known for its potential use in the synthesis of other sulfur-containing compounds and as a building block in the preparation of various coordination complexes. Its chemical structure features a central carbon atom bonded to two formamidine groups, each of which is connected to a sulfur atom, and the entire molecule carries two nitrate counterions.

76644-12-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76644-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,4 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76644-12:
(7*7)+(6*6)+(5*6)+(4*4)+(3*4)+(2*1)+(1*2)=147
147 % 10 = 7
So 76644-12-7 is a valid CAS Registry Number.

Kinetics and Mechanism of Reaction of Thiourea Nitrite in a Highly Ionic Medium

Pare, J. R. Jocelyn

, p. 1116 - 1119 (2007/10/02)

The title reaction proceeds by a multistep mechanism with two major paths.Production of colloidal sulphur is also noted.A novel mechanistic approach is proposed, based on the kinetic data obtained and some previous work.The reaction is shown to be a second-order process involving an unusual S-nitrosation of thiourea.
