831-51-6 Usage
General Description
3-amino-5-nitrosalicylic acid is a chemical compound with the molecular formula C7H6N2O5. It is a derivative of salicylic acid and is commonly used as a colorimetric reagent to detect the presence of nitrite ions in solution. The compound has a yellow to orange appearance and is soluble in water. It works by reacting with nitrite ions to form a diazonium salt, which can then be coupled with other compounds to produce a colored product. This reaction is often used in laboratory settings to quickly and easily detect the presence of nitrite ions, which can be indicative of various environmental and health concerns. Additionally, 3-amino-5-nitrosalicylic acid is also employed in the synthesis of pharmaceuticals and other organic compounds due to its versatile chemical properties.
Check Digit Verification of cas no
The CAS Registry Mumber 831-51-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 831-51:
(5*8)+(4*3)+(3*1)+(2*5)+(1*1)=66
66 % 10 = 6
So 831-51-6 is a valid CAS Registry Number.

Selective partial hydrogenation of dinitrobenzenes to nitroanilines catalyzed by Ru/C
Hou, Jie,Ma, Yonghuan,Li, Yuhan,Guo, Fang,Lu, Lianhai
scheme or table, p. 974 - 975 (2009/04/06)
Ru/C was found to be a highly effective catalyst for the selective partial hydrogenation of a range of dinitrobenzenes to their corresponding nitroanilines with excellent selectivity under mild conditions. Furthermore, the effect from other substitute groups of dinitrobenzenes on partial hydrogenation was also explored in this study. Copyright
