642-95-5 Usage
General Description
2,3,4-tribromoaniline is a chemical compound with the molecular formula C6H5Br3N. It is a derivative of aniline, with three bromine atoms substituted on the second, third, and fourth carbon positions of the benzene ring. 2,3,4-tribromoaniline is commonly used in organic synthesis and as an intermediate in the production of pharmaceuticals, dyes, and agrochemicals. It is also used as a precursor for various organic compounds and in the preparation of molecular materials. The compound is considered to be harmful if ingested, inhaled, or comes into contact with the skin, and should be handled with care in a well-ventilated area and with appropriate personal protective equipment.
Check Digit Verification of cas no
The CAS Registry Mumber 642-95-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 642-95:
(5*6)+(4*4)+(3*2)+(2*9)+(1*5)=75
75 % 10 = 5
So 642-95-5 is a valid CAS Registry Number.

Copper(I)-Induced Bromo-Hydrogen Exchange of 2,3-Dibromoanilines
Liedholm, Brita
, p. 877 - 884 (2007/10/02)
The copper(I)-induced bromine-hydrogen exchange reaction of 2,3-dibromoaniline and 5-substituted 2,3-dibromoanilines in the 2-position has been kinetically studied in water-acetic acid-hydrochloric acid medium at 90 deg C.The dehalogenation reaction is of second order, first order in both substrate and Cu+, and may be interpreted as a reductive substitution, composed of two one-electron steps.The 2,3-dibromophenol was only qualitatively investigated, but gave similar results.
