201026-82-6 Usage
Molecular structure
Consists of a pyridine ring with a nitro group at the 5-position and a trimethylsilyl-substituted ethynyl group at the 2-position.
Use in organic synthesis
Commonly used as a building block for the construction of more complex molecules.
Role in bond formation
Employed as a reagent in the formation of carbon-carbon and carbon-nitrogen bonds.
Reactivity
Capable of reacting with a variety of different functional groups.
Protection of alkynyl group
The trimethylsilyl group provides protection for the ethynyl functionality and can be easily removed under mild conditions to reveal the reactive alkynyl group.
Applications
Widely utilized in the field of organic chemistry for the production of pharmaceuticals, agrochemicals, and materials science applications.
Check Digit Verification of cas no
The CAS Registry Mumber 201026-82-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,0,2 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 201026-82:
(8*2)+(7*0)+(6*1)+(5*0)+(4*2)+(3*6)+(2*8)+(1*2)=66
66 % 10 = 6
So 201026-82-6 is a valid CAS Registry Number.

Metal-free synthesis of 2-alkenyl/alkynyl-5-nitropyridines using a three-component ring transformation
Le, Song Thi,Asahara, Haruyasu,Nishiwaki, Nagatoshi
, p. 776 - 778 (2015)
A metal-free, facile, and efficient protocol for synthesizing a series of 2-alkenyl/alkynyl-5-nitropyridines was developed by using a three-component ring transformation of 1-methyl-3,5- dinitro-2-pyridone with α,β-unsaturated ketones and ammonium acetate
