General Description
2,4-Dichlorophenyl 2,5-dichlorophenyl ether, also known as 2,4'-dichloro-2,5'-dimethoxydiphenyl ether, is a chemical compound with the molecular formula C12H8Cl4O2. It is a white crystalline solid that is used as a chemical intermediate in the production of herbicides and fungicides. The compound has been found to have potential endocrine-disrupting effects, and it is considered to be a persistent environmental pollutant. This chemical is not widely used or produced, and there is limited information available on its potential health effects and environmental impact. However, due to its structural similarity to other known pollutants, further research is needed to fully understand the potential risks associated with 2,4-Dichlorophenyl 2,5-dichlorophenyl ether.
Check Digit Verification of cas no
The CAS Registry Mumber 155999-92-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,9,9 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 155999-92:
(8*1)+(7*5)+(6*5)+(5*9)+(4*9)+(3*9)+(2*9)+(1*2)=201
201 % 10 = 1
So 155999-92-1 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.
