General Description
1H-1,2,4-Triazole, 3-iodo- is a chemical compound with the molecular formula C2H2IN3. It is a halogenated derivative of 1,2,4-triazole, which is a five-membered heterocyclic compound. 1H-1,2,4-Triazole, 3-iodo- is primarily used in organic synthesis as a building block for the preparation of pharmaceuticals and agrochemicals. It is also used as a ligand in coordination chemistry and as a precursor for the synthesis of various other functionalized triazole derivatives. As a halogenated compound, 1H-1,2,4-Triazole, 3-iodo- may possess potential hazards and should be handled and used with caution in a laboratory setting.
Check Digit Verification of cas no
The CAS Registry Mumber 7411-20-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,1 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7411-20:
(6*7)+(5*4)+(4*1)+(3*1)+(2*2)+(1*0)=73
73 % 10 = 3
So 7411-20-3 is a valid CAS Registry Number.

Micelle Activated Reactions I. Micelle Activated Iodination and Partial Dehalogenation of Pyrazoles and 1,2,4-Triazoles

A method is described to iodinate pyrazole, substituted pyrazoles or 1,2,4-triazole with iodine or iodine chloride in aqueous alkaline in the presence of an anionic surfactant. 4-Iodo- (2a), 4-iodo-3(5)-methyl- (2b), 3(5),4-diiodo- (3a), 3(5),4-diiodo-5(3)-methyl- (3b), and 3,4,5-triiodo-pyrazole (3d) as soon as 4-iodo-pyrazole-3(5)-carboxylic acid (2c), and 3(5)-iodo-1,2,4-triazole (5) were prepared.Anhydrous hydrogen fluoride or triethylamine trishydrofluoride were found to be a suitable agent to effect a regioselective partial dehalogenation of 3b, 3d and 3,5-dibromo-1,2,4-triazole (7).We prepared 3(5)-iodo-5(3)-methyl-pyrazole (6b), 3,5-diiodo-pyrazole (6d) and 3(5)-bromo-1,2,4-triazole (8) on this way.
