91732-68-2 Usage
Molecular weight
Higher than regular 1-butanol (The presence of seven deuterium atoms increases the molecular weight of the compound)
Stability
Stable isotope-labeled form (The deuterium atoms make the compound more stable and less reactive)
Usage
Used as a labeled standard or internal standard in gas chromatography-mass spectrometry (GC-MS) and other analytical methods (The deuterated form helps in accurately measuring and identifying the presence and quantity of 1-butanol in various samples)
Application
Valuable tool in research and industrial applications (It helps in the analysis of complex mixtures and the identification of specific chemicals)
Deuterium atoms
Seven (The compound contains seven deuterium atoms, making it heavier than regular 1-butanol)
Check Digit Verification of cas no
The CAS Registry Mumber 91732-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,3 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91732-68:
(7*9)+(6*1)+(5*7)+(4*3)+(3*2)+(2*6)+(1*8)=142
142 % 10 = 2
So 91732-68-2 is a valid CAS Registry Number.

The carbon skeleton of the azamacrolide epilachnene, the principal defensive alkaloid of Epilachna varivestis pupae, can be derived from oleic acid and serine. Analytical evidence from three experiments in which insects were fed (2H35)octadecanoic acid, (Z)-9- [11,11,12,12,13,13,14,14,15,15,16,16,17,17,18,18,18-2H17]octadecenoic acid and (Z)-9-[11,11,12,12,13,13,14,14,16,16,17,17,18,18,18-2H15]octadecenoic acid, indicates that only the C-15 methylene group of oleic acid is involved in the mechanism leading to carbon-nitrogen bond formation in epilachnene. Support for this scheme is provided by the observation of an unusual ion at m/z 170 in the electron-ionization mass spectrum of epilachnene, rationalized as CH2=CH-COO-CH2-CH2-NH+=CH-CH2-CH2-CH3.
