Dimethylphosphoryl cyanide, also known as DMPC, is a chemical compound with the formula (CH3)2P(O)CN. It is a colorless, volatile liquid that is soluble in organic solvents. DMPC is a toxic organophosphorus compound, which means it contains carbon and phosphorus atoms bonded together. It is used as a precursor in the synthesis of various organophosphorus compounds, including pesticides and chemical warfare agents. Due to its potential use in the production of chemical weapons, DMPC is a controlled substance under international regulations. It is important to handle DMPC with extreme caution, as it can cause severe health issues and environmental damage.

3583-90-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3583-90-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,8 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3583-90:
(6*3)+(5*5)+(4*8)+(3*3)+(2*9)+(1*0)=102
102 % 10 = 2
So 3583-90-2 is a valid CAS Registry Number.

Investigations on Diazo Compounds and Azides, XLIII. 1,2-Dewarpyridazines - Suitable Precursors for the Generation of Azacyclobutadienes?

Eisenbarth, Philipp,Regitz, Manfred

, p. 445 - 454 (2007/10/02)

Heating of the (diazomethyl)cyclopropenes 9b and c yields the pyridazines 10b and c as main products.The formation of the carbenes 11b and c, which decompose into the acetylenes 12 and 13, competes with the isomerization reaction.The pyridazine 10d is obtained immediately by electrophilic diazoalkane substitution of 6 with the cyclopropenylium salt 8; 9d can be established as intermediate by IR spectroscopy.The irradiation of the pyridazines 10a-d (10a is described in literature) leads to the stable 1,2-Dewarpyridazines 15a-d.The flash pyrolysis of 15b, conducted exemplarily, affords the fragment pairs 16 and 13b as well as 12 and 20.Their formation is in agreement with the intermediacy of the valence tautomeric azacyclobutadienes 1718.
