216983-03-8 Usage
Description
2,4,7-Trimethyldibenzothiophene is an organic compound that belongs to the class of dibenzothiophenes, which are heterocyclic compounds containing a sulfur atom. It is characterized by the presence of three methyl groups attached to the benzene rings, which contribute to its unique chemical properties and potential applications.
Uses
Used in Petroleum Industry:
2,4,7-Trimethyldibenzothiophene is used as a biomarker for determining the maturity of crude oil. Its presence and concentration in crude oil can provide valuable information about the thermal history and maturation level of the oil, which is crucial for assessing the potential of oil reserves and guiding exploration strategies.
Check Digit Verification of cas no
The CAS Registry Mumber 216983-03-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,9,8 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 216983-03:
(8*2)+(7*1)+(6*6)+(5*9)+(4*8)+(3*3)+(2*0)+(1*3)=148
148 % 10 = 8
So 216983-03-8 is a valid CAS Registry Number.

N-Benzyldithiocarbamate Salts as Sulfur Sources to Access Tricyclic Thioheterocycles Mediated by Copper Species

Using an easily prepared triethylammonium N-benzyldithiocarbamate salt as a sulfur source, a dual C?S functionalization of cyclic diaryliodoniums to form tricyclic thioheterocycles is realized. Our method uses the readily available copper sulfate to accelerate the chemical transformation under mild conditions. A broad range of cyclic diaryliodoniums with a ring size from 5- to 7-membered can be employed to gain a quick access to tricyclic thioheterocycles including dibenzothiophenes, thioxanthenes, and phenoxathiines. (Figure presented.).
