1758-62-9 Usage
General Description
PYRAZINE-D4 is a deuterated form of pyrazine, a heterocyclic aromatic organic compound with a nitrogen atom in the 1 and 4 positions of the six-membered ring. It is commonly used as a flavor and fragrance additive in the food and beverage industry due to its strong, nutty, and earthy aroma. PYRAZINE-D4 is also used in the pharmaceutical industry as a building block in the synthesis of various drugs and compounds. Its deuterated form, PYRAZINE-D4, contains four deuterium atoms, making it useful as a stable isotope-labeled standard for mass spectrometry and NMR analysis in research and analytical laboratories.
Check Digit Verification of cas no
The CAS Registry Mumber 1758-62-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,5 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1758-62:
(6*1)+(5*7)+(4*5)+(3*8)+(2*6)+(1*2)=99
99 % 10 = 9
So 1758-62-9 is a valid CAS Registry Number.

Rotational Lattice Vibrations of - and Pyrazine Crystals

, p. 925 - 927 (1989)
Low-frequency Raman bands of the - and pyrazine crystals were studied at various temperatures between 4.2 and 300 K.All six rotational lattice vibrations were identified based on the isotopic factor (the ratio of the vibrational frquency of the - and pyrazine crystals) of the individual vibrations.Classification of the rotational lattice vibrations into symmetry species was made through the polarisation measurement of the Raman bands in single crystals.
