(4-Chlorphenyl)-(2,4-dinitrophenyl)-sulfoxid, also known as 4-chlorophenyl 2,4-dinitrophenyl sulfoxide, is an organic compound with the chemical formula C12H6ClNO4S. It is a derivative of a sulfoxide, which is a sulfur-containing functional group with a sulfur atom bonded to an oxygen atom and two carbon atoms. (4-Chlorphenyl)-(2,4-dinitrophenyl)-sulfoxid is characterized by the presence of a 4-chlorophenyl group and a 2,4-dinitrophenyl group connected through a sulfur-oxygen bond. It is a yellow crystalline solid and is used as an intermediate in the synthesis of various organic compounds, particularly in the production of pharmaceuticals and agrochemicals. Due to its reactive nature and potential toxicity, it is important to handle (4-Chlorphenyl)-(2,4-dinitrophenyl)-sulfoxid with care and in accordance with proper safety protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 966-72-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,6 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 966-72:
(5*9)+(4*6)+(3*6)+(2*7)+(1*2)=103
103 % 10 = 3
So 966-72-3 is a valid CAS Registry Number.

VARIATION OF THE VALENCE OF SULFUR IN SUBSTITUTED 2,4-DINITROPHENYL PHENYL SULFOXIDES IN REARRANGEMENT PROCESSES

, p. 944 - 949 (2007/10/02)

The oxidation of the bridging sulfur atom in diphenyl sulfides, leading to the formation of sulfoxides and sulfones, was investigated.The various rearrangement processes which occur in substituted 2,4-dinitrophenyl phenyl sulfoxides during electron impact and lead to the appearance of characteristic fragment ions were demonstrated.The effect of the nature of substituents on the main directions in mass-spectrometric dissociation was investigated, and a correlation was obtained between log Z'/Z for the fragment due to elimination of the bridging SO group from the molecular ion and the Hammett ? constants.
