t-Amyloxycarbonylazid, also known as t-AOC, is a chemical compound with the molecular formula C10H17N3O5. It is a protected form of the azide group, commonly used in organic synthesis and peptide chemistry. t-AOC serves as a protecting group for the azide functionality, which is crucial in various chemical reactions, such as the Staudinger ligation and the Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC). These reactions are essential for the formation of peptide bonds and the synthesis of complex molecules, including bioconjugates and pharmaceuticals. The t-AOC protecting group can be selectively removed under mild conditions, making it a valuable tool in the synthesis of sensitive compounds.
The CAS Registry Mumber 5591-72-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,9 and 1 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5591-72: (6*5)+(5*5)+(4*9)+(3*1)+(2*7)+(1*2)=110 110 % 10 = 0 So 5591-72-0 is a valid CAS Registry Number.
