38444-77-8 Usage

General Description

2,4',6-Trichlorobiphenyl, also known as PCB 30, is a type of polychlorinated biphenyl (PCB) that is composed of three chlorine atoms attached to a biphenyl molecule. This chemical is a persistent organic pollutant that has been used in various industrial and commercial applications, such as in electrical equipment, hydraulic fluids, and sealants. However, due to its toxicity and negative environmental impact, PCBs have been banned in many countries. 2,4',6-Trichlorobiphenyl is known to be a potential carcinogen and can cause serious health effects in humans and wildlife. It is also known to bioaccumulate in the food chain, leading to widespread contamination in the environment. As a result, efforts are underway to clean up and safely dispose of PCBs to minimize their harmful effects on ecosystems and human health.

Check Digit Verification of cas no

The CAS Registry Mumber 38444-77-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,4,4 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 38444-77:
(7*3)+(6*8)+(5*4)+(4*4)+(3*4)+(2*7)+(1*7)=138
138 % 10 = 8
So 38444-77-8 is a valid CAS Registry Number.

Low-Temperature Ag/Pd-catalyzed decarboxylative cross-coupling of aryl trflates with aromatic carboxylate salts

Goossen, Lukas J.,Lange, Paul P.,Rodriguez, Nuria,Linder, Christophe

supporting information; experimental part, p. 3906 - 3909 (2010/07/03)

Chemical Equation Presented At 50°C lower than the best known copper catalysts, a catalytic silver(I)/ palladium(II) system allows the decarboxylative cross-coupling of arenecarboxylates with aryl triflates at temper-atures as low as 120°C. Remarkably, polychlorinated and many heterocyclic arenecarboxylates are converted for the first time in high yields. FG = functional group.

Physical, spectral and chromatographic properties of all 209 individual PCB congeners

Bolgar,et al.

, p. 2687 - 2705 (2007/10/03)

Through the use of two capillary GC columns: 40% octadecyl/ 15% phenyl methyl siloxane and 50% phenyl methyl siloxane, it was possible to separate 201 PCB congeners with only four unresolved pairs. The data compiled in this study for all 209 congeners will aid in the identification of selected individual components of these environmental pollutants. The use of this data also presents the opportunity for the improved quantification of the commercial PCB formulations. -from Authors
