Uses

Used in Chemical Synthesis:
1,1'-Oxybis(3,4-dichlorobenzene) is used as an intermediate in the chemical synthesis of 2,3,7,8-Tetrachlorodibenzofuran (T291375), a toxic polychlorinated dibenzofuran. 1,1'-Oxybis(3,4-dichlorobenzene) has been detected in domestic meat and poultry, highlighting the importance of understanding and controlling the synthesis process to minimize potential health risks.

Check Digit Verification of cas no

The CAS Registry Mumber 56348-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,3,4 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 56348-72:
(7*5)+(6*6)+(5*3)+(4*4)+(3*8)+(2*7)+(1*2)=142
142 % 10 = 2
So 56348-72-2 is a valid CAS Registry Number.

Synthesis, Structure Verification, and Chromatographic Relative Retention Times for Polychlorinated Diphenyl Ethers

Nevalainen, Tapio,Koistinen, Jaana,Nurmela, Pirjo

, p. 1341 - 1347 (2007/10/03)

Fifty-four polychlorinated diphenyl ether (PCDEs) congeners were synthesized, and their structures were confirmed by mass spectrometry and proton magnetic resonance spectroscopy. The gas chromatographic relative retention times (RRT) for the PCDEs were determined relative to a reference standard, -tetrachlorobiphenyl (PCB 77) on the fused silica capillary columns of SE-54 and OV-1701. The retention times for PCDEs increased with the increasing number of vicinal chlorines within a series of isomers. The chlorine substitution patterns of PCDEs were used to develop a method for predicting RRTs for congeners that were not synthesized.
