Description
Dibromomalononitrile, with the chemical formula C3NBr2, is a synthetic organic compound that appears as a white crystalline solid. It is highly toxic and has been known to be used as a chemical warfare agent.
Uses
Used in Riot Control:
Dibromomalononitrile is used as a riot control agent, causing severe eye, skin, and respiratory irritation. Its potent effects make it a deterrent in crowd control situations.
Used in Chemical Warfare:
Due to its toxicity, dibromomalononitrile has been used as a chemical warfare agent, although its use is strictly regulated and controlled.
Used in Dye Production:
Dibromomalononitrile is used in the production of some types of dyes, but its application in this industry is limited due to its hazardous nature.
Used in Pharmaceutical Industry:
dibromomalononitrile is also utilized in the production of certain pharmaceuticals, albeit with strict control measures in place to mitigate its potential risks.
Regulation:
Due to its toxicity and potential for misuse, dibromomalononitrile is classified as a Schedule 3 substance under the Chemical Weapons Convention, ensuring that its production, use, and trade are subject to stringent international oversight.
Check Digit Verification of cas no
The CAS Registry Mumber 1885-23-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,8 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1885-23:
(6*1)+(5*8)+(4*8)+(3*5)+(2*2)+(1*3)=100
100 % 10 = 0
So 1885-23-0 is a valid CAS Registry Number.

!,3-Dipolar cycloaddition of α-phenyl-N-tert-butylnitrone (PBN) to dichloro- and dibromo-malononitrile, chlorotricyanomethane and tetracyanomethane. Structure of products and kinetics of their formation

The kinetics of cycloaddition between α-phenyl-N-tert-butylnitrone (PBN, IUPAC name: N-benzylidene-tert-butylamine N-oxide) and six activated nitriles R-CN, viz. dibromo- and dichloro-malononitrile (1a and 1b), chlorotricyanomethane (1c), tetracyanomethane (1d), trichloroacetonitrile (1e) and carbamoylchlorodicyanomethane (5), to give 2-tert-butyl-3-phenyl-5-R-2,3-dihydro-1,2,4-oxadiazoles 2a-e have been determined, as well as the similar reaction between 4-NO2PBN and 1c.The second-order rate constants for reaction between PBN and 1 in acetonitrile fall (relative rate constant in parenthesis) in the order of 1d (5.4*103) > 1c (3.1*102) > 1b (8) > 5 (not given) > 1e (9*10-3).The rate constants are slightly larger in non-polar solvents.The rate constants of the PNB-1c and PNB-1d cycloadditions (0.15 and 2.6 dm3 mol-1 s-1, respectively) are of the same magnitude as those recently used to classify thioketones as 'superdipolarophiles'.X-Ray crystal structures are reported for 2-tert-butyl-3-phenyl-5-(dichlorocyanomethyl)-2,3-dihydro-1,2,4-oxadiazole (2b) and 2-tert-butyl-3-phenyl-5-(chlorodicyanomethyl)-2,3-dihydro-1,2,4-oxadiazole (2c).
