Uses
1-Aminopyridinium iodide is a reagent used as a building block to construct fused heterocycles, synthesis of substituted pyridines, dipolar cycloadditions, ylide type reactions.
General Description
1-Aminopyridinium iodide, a pyridine derivative, is an important reagent for organic synthesis. It has various pharmaceutical applications. It participates in homogeneous transition metal-catalyzed reactions. Single-crystal X-ray diffraction studies suggest that the compound crystallizes in the monoclinic space group P21/c (phase II). Aza-ylide derived from 1-aminopyridinium iodide serves as a commercially available ammonia equivalent during the preparation of primary amines.
Check Digit Verification of cas no
The CAS Registry Mumber 6295-87-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,9 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6295-87:
(6*6)+(5*2)+(4*9)+(3*5)+(2*8)+(1*7)=120
120 % 10 = 0
So 6295-87-0 is a valid CAS Registry Number.

Aminopyridinium iodide as a NH transferring agent for the synthesis of 2-aroyl-3-aryl aziridines
Samimi, Heshmat A.,Momeni, Ahmad R.
, p. 2221 - 2225 (2015/10/19)
A new approach for the synthesis of N-H ketoaziridines is described. 1-aminopyridinium iodide as a NH transferring agent provides a straightforward access to the 2-aroyl-3-arylaziridines from the corresponding 1,3-diarylprop-2-en-1-one. A possible general mechanism involving the N-N ylide is proposed.
