4-NITRO-PYRIDIN-3-YLAMINE, also known as 4-nitropyridin-3-ylamine, is a chemical compound with the molecular formula C5H5N3O2. It is a yellow crystalline solid and is commonly used as a building block in organic synthesis and pharmaceutical research. 4-NITRO-PYRIDIN-3-YLAMINE is known for its nitrogen-containing heterocyclic structure, which makes it a versatile intermediate for the synthesis of various pharmaceuticals and agrochemicals. It is also used in the production of dyes and pigments. However, it is important to handle this compound with caution as it can be toxic and may cause irritation to the skin, eyes, and respiratory system if not properly handled.
Check Digit Verification of cas no
The CAS Registry Mumber 13505-02-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,0 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13505-02:
(7*1)+(6*3)+(5*5)+(4*0)+(3*5)+(2*0)+(1*2)=67
67 % 10 = 7
So 13505-02-7 is a valid CAS Registry Number.

SYNTHESES WITH AROMATIC NITRAMINES, V. PHOTOCHEMICAL REARRANGEMENT OF NITRAMINOPYRIDINES

, p. 159 - 164 (2007/10/02)
All three isomeric nitraminopyridines were photolysed in methanol with low-pressure mercury lamp (253.7 nm). 2-Nitraminopyridine yielded both 2-amino-3-nitro- and 2-amino-5-nitropyridines (isomer ratio 6.26 : 1). 3-Nitropyridine rearranged into both 4-nitro- and 2-nitro-3-aminopyridines (isomer ratio 1.28 : 1), whereas 4-nitraminopyridine gave 3-nitro-4-aminopyridine as the sole product. 1-Methyl-2-nitriminopyridine did not rearrange under the conditions applied, but 1-methyl-4-nitriminopyridine gave 3-nitro-4-methylaminopyridine.The latest product was also obtained when the same starting material was rearranged in conc. sulfuric acid.
