22364-56-3 Usage
General Description
AMMONIA (15N; D3) is a variant of ammonia, a compound consisting of one nitrogen and three hydrogen atoms, where the nitrogen atom is the stable isotope 15N and three of the hydrogen atoms are the stable isotope D3 (deuterium). AMMONIA (15N; D3) is commonly used in scientific research as a tracer or labeled compound for studying nitrogen metabolism, protein turnover, and other biochemical processes. The use of stable isotopes in ammonia allows for tracking the movement and transformation of nitrogen in biological systems, providing valuable insights into various metabolic pathways and processes. Additionally, the incorporation of deuterium in ammonia can also be useful for studies involving hydrogen exchange and other chemical reactions.
Check Digit Verification of cas no
The CAS Registry Mumber 22364-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,3,6 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 22364-56:
(7*2)+(6*2)+(5*3)+(4*6)+(3*4)+(2*5)+(1*6)=93
93 % 10 = 3
So 22364-56-3 is a valid CAS Registry Number.

Surface-nitrogen removal in a steady-state NO + H2 reaction on Pd(110)
Ma, Yunsheng,Matsushima, Tatsuo
, p. 1256 - 1261 (2007/10/03)
Surface-nitrogen removal steps were analyzed in the course of a catalyzed NO + H2 reaction on Pd(110) by angle-resolved mass spectroscopy combined with cross-correlation time-of-flight techniques. Four removal steps, i.e., (i) the associative process of nitrogen atoms, 2N(a) → N 2(g), (ii) the decomposition of the intermediate, NO(a) + N(a) → N2O(a) → N2(g) + O(a), (iii) its desorption, N 2O(a) → N2O(g), and (iv) the desorption as ammonia, N(a) + 3H(a) → NH3(g), are operative in a comparable order. Above 600 K, process (i) is predominant, whereas the others largely contribute below 600 K. Process (iv) becomes significant at H2 pressures above a critical value, about half the NO pressure. Hydrogen was a stronger reagent than CO toward NO reduction and relatively enhanced the N(a) associative process.
