Aniline, also known as aminobenzene, is an organic compound with the chemical formula C6H5NH2. It is a colorless oily liquid that is soluble in water and serves as an important intermediate in the chemical industry, used in the production of dyes, pharmaceuticals, and various other chemicals. On the other hand, the salt of 4-nitro-phenol refers to a group of compounds formed by the reaction of 4-nitrophenol with various acids, resulting in salts such as 4-nitrophenol sodium salt or 4-nitrophenol potassium salt. These salts are often used in analytical chemistry as indicators in titrations and as reagents in organic synthesis. Both aniline and the salts of 4-nitro-phenol are significant in their respective fields, with aniline being a key precursor in the synthesis of various chemicals, while the salts of 4-nitro-phenol are valuable for their applications in chemical analysis and synthesis.

7274-03-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7274-03-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,7 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7274-03:
(6*7)+(5*2)+(4*7)+(3*4)+(2*0)+(1*3)=95
95 % 10 = 5
So 7274-03-5 is a valid CAS Registry Number.

Aromatic Nucleophilic Substitution Reactions of Some 2-L-3-Nitro-5-X-thiophenes with Piperidine and Aniline in Methanol. Substituent Constants for the Thiophene System

Consiglio, Giovanni,Frenna, Vincenzo,Arnone, Caterina,Mezzina, Elisabetta,Spinelli, Domenico

, p. 2187 - 2190 (2007/10/02)

The rate constants for the reactions of some 2-L-3-nitro-5-X-thiophenes 1-4 with aniline and of compounds (4) with piperidine in methanol have been measured at various temperatures.By using the data obtained in this work as well as previously available data sets, a series of optimized 'thiophene' ?τ values has been calculated.The susceptibility constants ρ(L) of the various sets have been analysed in the framework of the reactivity-selectivity principle.
