General Description
4-Amino-2-ethylpyridine is an aromatic organic compound known for its applications in various industrial processes. It exists as a liquid at room temperature. This chemical substance is found in the pyridine family of compounds which contain one or more ring nitrogen atoms. It is readily soluble in water and also shows solubility in common organic solvents. The presence of an amine group (-NH2) and an ethyl group (-C2H5) makes it a functional derivative of pyridine. It is manufactured and used primarily in the pharmaceutical and chemical industries, often as an intermediate in the production of more complex chemicals. It is also used as a catalyst and a corrosion inhibitor. However, exposure to 4-Amino-2-ethylpyridine may cause irritation to the skin, eyes, and respiratory tract, so protective measures are important while handling this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 50826-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,8,2 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 50826-64:
(7*5)+(6*0)+(5*8)+(4*2)+(3*6)+(2*6)+(1*4)=117
117 % 10 = 7
So 50826-64-7 is a valid CAS Registry Number.

Preparation of carbon-14 labeled N-(2-ethyl-3-chloro-4-pyridinyl)-4 -(4-chlorophenoxy)phenylacetamide
Pearson
, p. 151 - 157 (2007/10/03)
A 4-step modified route has been developed for the synthesis of N-(2-ethyl-3-chloro-4-pyridinyl-2-[14C])-4-(4-chloro- phenoxy)phenylacetamide ([14C]-1). The key transformation in the sequence is an amination/cyclization pair of reactions that furnished 2-[14C]-4-amino-2-ethylpyridine (4) from 5-[14C]-1-methoxyhept-1-en-3-yn-5-one (3) and ammonia. Amine 4 was then selectively chlorinated to provide 2-[14C]-4-amino-3-chloro-2-ethylpyridine (5) which was then coupled with 4-(4-chlorophenoxy)phenylacetic ethylformic anhydride (6) in a reaction mediated by trimethylaluminum to furnish the desired, radiolabeled phenylacetamide [14C]-1.
