General Description
2,4-Dichloro-5-[3,4,5-trimethoxybenzyl]pyrimidine is a chemical compound that contains two chlorine atoms and a pyrimidine ring with a benzyl group attached to it. The benzyl group is further substituted with three methoxy groups at the 3rd, 4th, and 5th positions. This chemical is often used as a building block or intermediate in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. It may also possess biological activity and can be used as a research tool in the development of new drugs or agrochemicals. 2,4-Dichloro-5-[3,4,5-trimethoxybenzyl]pyrimidine's specific properties and applications can vary depending on its exact structure and purity.
Check Digit Verification of cas no
The CAS Registry Mumber 55694-05-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,6,9 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 55694-05:
(7*5)+(6*5)+(5*6)+(4*9)+(3*4)+(2*0)+(1*5)=148
148 % 10 = 8
So 55694-05-8 is a valid CAS Registry Number.

Synthesis of functionalized diarylmethanes via a copper-catalyzed cross-coupling of arylmagnesium reagents with benzylic phosphates
Kofink, Christiane C.,Knochel, Paul
, p. 4121 - 4124 (2007/10/03)
A combination of copper chloride, triethyl phosphite, and tetrabutylammonium iodide is a very efficient catalytic system for the synthesis of polyfunctionalized diarylmethanes, using the cross-coupling reaction of arylmagnesium halides with benzylic phosphates. The antibiotic Trimethoprim has been prepared using this Cu(I)-catalyzed cross-coupling in 52% overall yield (four steps).
