4185-79-9 Usage
General Description
2-bromo-1,3-dinitrobenzene is a chemical compound with the molecular formula C6H3BrN2O4. It is a yellow crystalline solid that is primarily used as an intermediate in the synthesis of pharmaceuticals, dyes, and other organic compounds. 2-bromo-1,3-dinitrobenzene is a powerful electrophile and is commonly employed in organic reactions such as the synthesis of substituted anilines and nitrobenzenes. It is also utilized as a starting material for the production of agricultural chemicals and other specialty chemicals. 2-bromo-1,3-dinitrobenzene is considered to be toxic and should be handled and disposed of with caution.
Check Digit Verification of cas no
The CAS Registry Mumber 4185-79-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,8 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4185-79:
(6*4)+(5*1)+(4*8)+(3*5)+(2*7)+(1*9)=99
99 % 10 = 9
So 4185-79-9 is a valid CAS Registry Number.

Thermal Stability Studies on a Homologous Series of Nitroarenes
Oxley, Jimmie C.,Smith, James L.,Ye, Hong,McKenney, Robert L.,Bolduc, Paul R.
, p. 9593 - 9602 (2007/10/02)
The thermal stabilities of a number of nitroarenes were examined in solution and in condensed phase.In general, increasing the number of nitro groups decreased thermal stability.Changing the substituent on 1-X-2,4,6-trinitrobenzene from X = H to NH2 to CH3 to OH accelerated decomposition; this effect was attributed to increased ease of intramolecular proton transfer to an ortho nitro group, thus weakening the carbon-nitrogen bond.In solution, the effect of increasing substitution from n = 1 to n = 3 on Xn(NO2)3C6H3-n was uniformly that of decreasing the thermal stability of the species.However, in condensed phase, results suggested that crystal habit may be more important than molecular structure; for X = Br, CH3, and NH2, the more substituted species was the more stable.
