3131-67-7 Usage
General Description
Linolenic acid, [9,12,15-1-14C] is a radioactive form of linolenic acid, an omega-3 fatty acid. It is a polyunsaturated fatty acid found in plant oils, particularly in seeds and nuts. This labeled compound is often used in research and studies to track the metabolism and distribution of linolenic acid in various biological systems. It is also used in studying the absorption, transportation, and metabolism of omega-3 fatty acids in the human body, as well as in experiments focused on understanding the role of these fatty acids in human health and disease.
Check Digit Verification of cas no
The CAS Registry Mumber 3131-67-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,3 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3131-67:
(6*3)+(5*1)+(4*3)+(3*1)+(2*6)+(1*7)=57
57 % 10 = 7
So 3131-67-7 is a valid CAS Registry Number.

A divergent synthesis of [1-14C]-mono-E isomers of fatty acids
Georgin,Taran,Mioskowski
, p. 83 - 91 (2007/10/03)
A convenient synthesis of [1-14C]-mono-trans fatty acid using olefin inversion as a key-step is described. This methodology allows for a facile synthesis of [1-14C]-labelled mono-trans analogues of oleic, linoleic and linolenic acids. As an example, only eleven steps were necessary to obtain the [1-14C]-mono-E isomers of linolenic acid from its commercial all-Z form. In the first step, Barton's decarboxylation procedure yielded a bromo intermediate. Epoxidation of this compound resulted in the formation of three monoepoxides, which could be separated by HPLC. After identification by 1H NMR and MS, the pure monoepoxides were then subjected to inversion consisting of a stereospecific deoxygenation followed by a β-elimination step. Finally, the labelling was introduced by substitution of the bromine by a [14C]-cyano group followed by hydrolysis.
