N6-benzoyl-N2-trifluoroacetyl-L-lysine is a complex organic compound that features a lysine molecule, an essential amino acid, with two acyl modifications. The N6 position of the lysine side chain is acylated with a benzoyl group, while the N2 position, which is part of the lysine's amino group, is acylated with a trifluoroacetyl group. N6-benzoyl-N2-trifluoroacetyl-L-lysine is not a naturally occurring substance but is rather synthesized for specific applications, such as in chemical biology to study protein modifications or as a potential pharmaceutical intermediate. The presence of the trifluoroacetyl group, in particular, introduces a strong electron-withdrawing effect, which can significantly alter the reactivity and properties of the lysine residue in comparison to the unmodified amino acid.
The CAS Registry Mumber 326-51-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 6 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 326-51: (5*3)+(4*2)+(3*6)+(2*5)+(1*1)=52 52 % 10 = 2 So 326-51-2 is a valid CAS Registry Number.
