General Description
2-Aminopyridine-d6 is a deuterated derivative of 2-aminopyridine, an aromatic amine used in organic synthesis and pharmaceutical research. The deuterium substitution at the 6 position of the pyridine ring allows for easy tracking and identification of the compound using analytical techniques such as nuclear magnetic resonance (NMR) spectroscopy. 2-Aminopyridine-d6 is a stable, non-radioactive isotope that can be used as a labeled internal standard in analytical chemistry and biochemical research, providing accurate and precise measurement of compound concentrations in complex mixtures. Its deuterated form enhances its properties as a chemically inert and low-risk compound, making it a valuable tool in scientific exploration and analysis.
Check Digit Verification of cas no
The CAS Registry Mumber 203784-57-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,7,8 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 203784-57:
(8*2)+(7*0)+(6*3)+(5*7)+(4*8)+(3*4)+(2*5)+(1*7)=130
130 % 10 = 0
So 203784-57-0 is a valid CAS Registry Number.

A protocol of a versatile H-D exchange reaction of heterocyclic compounds catalyzed by heterogeneous Pd/C in D2O is described. The reaction of various nitrogen-containing heterocycles with 10% Pd/C (10 wt % of the substrate) under hydrogen atmosphere in D2O as a deuterium source at 110-180 °C for 24 h afforded the corresponding deuterated compounds with satisfactory efficiency of deuteration in moderate to excellent isolated yields. Furthermore, the Pd/C-H2-D2O system can be extended to the direct deuteration of biologically active compounds such as sulfamethazine, which is used as a synthetic antibacterial drug for fat stocks and would be applied as a general method for the preparation of the standard materials for the analysis of residual chemicals in foods and so on.
