3,3-d2-2-pyrrolidone, also known as deuterated 2-pyrrolidone, is a chemical compound with the molecular formula C4D2NO. It is a deuterated analog of the parent compound 2-pyrrolidone, which is a cyclic amide and a heterocyclic compound. The deuteration of 2-pyrrolidone involves the replacement of two hydrogen atoms with deuterium atoms, resulting in a molecule that is heavier and has different chemical properties compared to the parent compound. This deuterated version is often used in scientific research and industrial applications, particularly in the field of nuclear magnetic resonance (NMR) spectroscopy, where it can provide valuable information about the structure and dynamics of molecules. Additionally, deuterated compounds like 3,3-d2-2-pyrrolidone can be used in isotope labeling studies to trace chemical reactions and metabolic pathways.
The CAS Registry Mumber 930-78-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 0 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 930-78: (5*9)+(4*3)+(3*0)+(2*7)+(1*8)=79 79 % 10 = 9 So 930-78-9 is a valid CAS Registry Number.
