L-Histidine, N-(trifluoroacetyl)-, methyl ester is a chemical compound with the molecular formula C9H10F3N2O4. It is a derivative of the amino acid L-histidine, where the imidazole ring nitrogen is trifluoroacetylated, and the carboxylic acid group is esterified with a methyl group. L-Histidine, N-(trifluoroacetyl)-, methyl ester is often used in peptide synthesis and as a reagent in organic chemistry. Its unique structure, featuring the trifluoroacetyl group, provides it with enhanced reactivity and stability compared to other histidine derivatives. The compound is typically synthesized through the reaction of L-histidine with trifluoroacetic anhydride followed by methylation. It is an important building block in the preparation of complex peptides and has applications in the development of pharmaceuticals and other bioactive molecules.
The CAS Registry Mumber 1604-44-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 4 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 1604-44: (6*1)+(5*6)+(4*0)+(3*4)+(2*4)+(1*4)=60 60 % 10 = 0 So 1604-44-0 is a valid CAS Registry Number.
