38749-81-4 Usage
General Description
3-Bromo-2-ethylpyridine is an organic compound classified under aromatic heterocyclic compounds. It is specifically a pyridine compound, which means that its structure contains a six-membered aromatic ring with one nitrogen atom replacing a carbon atom. The compound has an ethyl group (-C2H5) attached to the second carbon atom and a bromine atom attached to the third carbon atom on the pyridine ring. The Chemical Abstracts Service (CAS) registry number for 3-Bromo-2-ethylpyridine is 7508-34-7. It is generally used in the field of organic synthesis and pharmaceuticals. The toxicity, reactivity, and other physical and chemical properties may vary, so it is important to handle this compound following the recommended safety guidelines.
Check Digit Verification of cas no
The CAS Registry Mumber 38749-81-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,7,4 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 38749-81:
(7*3)+(6*8)+(5*7)+(4*4)+(3*9)+(2*8)+(1*1)=164
164 % 10 = 4
So 38749-81-4 is a valid CAS Registry Number.

Paragraph 0032-0049, (2019/11/14)
The invention discloses a synthesis method for 3-bromine-2-ethylpyridine. The method comprises the steps that 2,3-bromopyridine is taken as the raw material and reacts with diethylzinc under the effect of a catalyst to obtain the 3-bromine-2-ethylpyridine. Although, there are many reports about application of the 3-bromine-2-ethylpyridine in medicine synthesis, synthesis routes for the 3-bromine-2-ethylpyridine are not reported. According to the synthesis method, a synthesis route is proposed for the first time, by-products are reduced, the high-yield high-purity 3-bromine-2-ethylpyridine is prepared, and reaction conditions are mild.
