159528-75-3 Usage
General Description
3-Methoxybenzonitrile-cyano-13C is a chemical compound that contains a 13C isotope. It is also known as 3-methoxybenzonitrile-13C and has the chemical formula C8H6NO. This labeled compound is commonly used in nuclear magnetic resonance (NMR) and mass spectrometry (MS) studies as a reference standard or internal standard for quantitative analysis. Its unique labeling with the 13C isotope allows for accurate determination of chemical shifts and quantification of the compound in mixtures. It is important to handle this compound with caution and follow proper safety guidelines when working with it in a laboratory setting.
Check Digit Verification of cas no
The CAS Registry Mumber 159528-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,5,2 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 159528-75:
(8*1)+(7*5)+(6*9)+(5*5)+(4*2)+(3*8)+(2*7)+(1*5)=173
173 % 10 = 3
So 159528-75-3 is a valid CAS Registry Number.

The synthesis of multiply 13C-labelled plant and mammalian lignans as internal standards for LC-MS and GC-MS analysis
Fryatt, Tara,Botting, Nigel P.
, p. 951 - 969 (2007/10/03)
The syntheses of multiply 13C-labelled derivatives of the two mammalian lignans, enterolactone and enterodiol, and two of their plant lignan precursors, secoisolariciresinol and matairesinol, are described. Three 13C atoms were incorporated into each lignan using potassium [ 13C]cyanide as the source for all of the 13C atoms. The compounds were prepared for use as internal standards in the LC-MS and GC-MS analysis of lignans. Copyright
A convenient method for cyanation of aromatic iodo compounds
Carr,Cable,Wells,Sutherland
, p. 887 - 897 (2007/10/02)
A variety of [13C]-labelled aromatic nitriles have been prepared in good yield from iodoaromatic substrates. Cyanation was achieved by reaction of aryl iodides with a mixture of potassium [13C]cyanide and copper (I)iodide in an aprot
