6602-34-2 Usage
General Description
2,4,6-TRIBROMO-3-PYRIDINOL is a chemical compound used as a flame retardant in various products, including plastics, textiles, and electronic components. It is an intermediate in the synthesis of brominated flame retardants and is also used as a biocide in wood preservation. 2,4,6-TRIBROMO-3-PYRIDINOL is an effective flame retardant due to its ability to suppress the combustion process and inhibit the spread of fire. It is classified as a hazardous substance and should be handled with caution due to its potential to cause skin and eye irritation, as well as respiratory issues if inhaled.
Check Digit Verification of cas no
The CAS Registry Mumber 6602-34-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,0 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6602-34:
(6*6)+(5*6)+(4*0)+(3*2)+(2*3)+(1*4)=82
82 % 10 = 2
So 6602-34-2 is a valid CAS Registry Number.

Mild regioselective halogenation of activated pyridines with N-bromosuccinimide
Canibano,Rodriguez,Santos,Sanz-Tejedor,Carreno,Gonzalez,Garcia-Ruano
, p. 2175 - 2179 (2007/10/03)
Regioselective mono and dihalogenations of amino, hydroxy and methoxy pyridines (2-, 3-, and 4-substituted) as well as 2,6-dimethoxy pyridine with N-bromosuccinimide in different solvents have been studied. Reactivity of the substrates decreases in the order amino>hydroxy>methoxy and regioselectivity depends on the position of the substituent (2-substituted > 3-substituted). In most of the cases we obtained monobrominated derivatives regioselectively and in high yields. Hydroxy and amino pyridines can also be dibrominated in almost quantitative yield with 2 equivalents of NBS.
