General Description
Formamide-15N is a stable isotopic form of formamide, a chemical compound with the molecular formula HCONH2. It contains a substituted nitrogen atom with a mass number of 15, making it a useful tool for labeling molecules and studying their behavior in various biological and chemical processes. Formamide-15N is commonly used in nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry to track the movement and transformation of nitrogen-containing compounds. This labeled formamide is also employed in isotope dilution studies to quantify the amount of specific compounds in a sample. Additionally, formamide-15N is used in research to examine the origin and pathways of nitrogen metabolism in living organisms.
Check Digit Verification of cas no
The CAS Registry Mumber 1449-77-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,4 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1449-77:
(6*1)+(5*4)+(4*4)+(3*9)+(2*7)+(1*7)=90
90 % 10 = 0
So 1449-77-0 is a valid CAS Registry Number.

Synthesis of a 13C,15N labeled imidazole and characterization of the 2,5-endoperoxide and its decomposition
Kang,Foote
, p. 9623 - 9626 (2007/10/03)
A synthesis of 13C, 15N labeled imidazoles was developed which allows the direct detection of a transient 2,5-endoperoxide at -100°C. The endoperoxide was thoroughly characterized by 1H, 13C, and 15N NMR. Upon warming, the endoperoxide decomposes via a series of transient intermediates to 13CO2 and 1,2-diphenyl-ethanediimine.
