General Description
N-[2-[(2,6-dibromo-4-nitrophenyl)azo]-5-(diethylamino)phenyl]acetamide is a chemical compound with the chemical formula C20H22Br2N6O3. It is a bright yellow to orange solid that is commonly used as a dye and pigment in various industrial applications. It is synthesized by coupling 2,6-dibromo-4-nitroaniline with N,N-diethylaniline in the presence of acetic anhydride to form the corresponding diazonium salt, which is then coupled with N,N-diethylaniline under mild conditions to produce the final product. N-[2-[(2,6-dibromo-4-nitrophenyl)azo]-5-(diethylamino)phenyl]acetamide has potential applications in the field of organic synthesis, especially in the development of colorants, as well as in the pharmaceutical and medical industries as a chemical intermediate in the synthesis of various drugs.
Check Digit Verification of cas no
The CAS Registry Mumber 52583-53-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,5,8 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 52583-53:
(7*5)+(6*2)+(5*5)+(4*8)+(3*3)+(2*5)+(1*3)=126
126 % 10 = 6
So 52583-53-6 is a valid CAS Registry Number.

Synthesis and Spectral Characterization of Blue Dyes of the Benzene Series
Thiel, W.,Mayer, R.,Jauer, E.-A.,Modrow, H.,Dost, H.
, p. 497 - 514 (2007/10/02)
53 Donor-acceptor substituted azo dyes of the benzene series were prepared by diazonium-coupling reactions (1a-s) or halogen-cyanide exchange (->2a-x, 3a-j).Described are the preparation of the amines 4a-m and the coupling compounds 5a-t and the procedure of diazotizing and coupling.The colouristic and spectroscopic data show that compounds of the general formula 1 are excellent brilliant blue azo dyes usefull for dyeing polyester material.
