General Description

4-Amino-2,6-dibromopyridine is a chemical compound that belongs to the pyridine family. It is a derivative of pyridine with two bromine atoms and an amino group attached to the 2 and 6 positions, respectively. 4-Amino-2,6-dibromopyridine is commonly used in the synthesis of pharmaceuticals and agrochemicals. It is also utilized in the production of dyes and pigments, as well as in the manufacturing of various organic compounds. 4-Amino-2,6-dibromopyridine is known for its high reactivity and is handled with caution due to its potential hazards.

Check Digit Verification of cas no

The CAS Registry Mumber 39771-34-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,7,7 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 39771-34:
(7*3)+(6*9)+(5*7)+(4*7)+(3*1)+(2*3)+(1*4)=151
151 % 10 = 1
So 39771-34-1 is a valid CAS Registry Number.

The development of a practical and reliable large-scale synthesis of 2,6-diamino-4-bromopyridine

Nettekoven, Matthias,Jenny, Christian

, p. 38 - 43 (2013/09/05)

A novel, safer, and efficient synthetic route to 2,6-diamino-4-bromopyridine has been developed. In discovery research a five-step synthesis afforded 2,6-diamino-4-bromopyridine in 56% yield with a double Curtius rearrangement as a key transformation. Due to potential safety concerns on larger scale an alternative synthetic strategy was necessary. Starting from 2,4-dibromopyridine-N-oxide two complementary procedures have been developed to access 2,6-diamino-4-bromopyridine. The four-step procedure yielded in 28% overall, and the five-step procedure, in 33% overall 2,6-diamino-4-bromopyridine in a safe and straightforward manner using a regioselective 2,6-diamination reaction as key step. Additionally, a general route to unsymmetrical substituted pyridine N-oxide derivatives is disclosed.
