N-Undecanoyl-sulfanilic acid amide, also known as N-undecyl sulfanilamide, is a chemical compound with the molecular formula C17H29NO2S. It is a derivative of sulfanilamide, an antibacterial agent, where an undecyl chain (a hydrocarbon chain with 11 carbon atoms) is attached to the nitrogen atom. N-undecanoyl-sulfanilic acid amide is used in various applications, including as an intermediate in the synthesis of pharmaceuticals and as a chemical reagent. It is characterized by its ability to form a zwitterion, with the sulfonamide group acting as an anionic center and the terminal amine group acting as a cationic center. The compound is typically synthesized through the reaction of sulfanilamide with undecyl chloride or undecyl bromide. Due to its amphoteric nature, it can interact with both acidic and basic substances, which may contribute to its utility in certain chemical processes.
The CAS Registry Mumber 6720-17-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,2 and 0 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 6720-17: (6*6)+(5*7)+(4*2)+(3*0)+(2*1)+(1*7)=88 88 % 10 = 8 So 6720-17-8 is a valid CAS Registry Number.
