L-Methionine, N-(trifluoroacetyl)- is a chemical compound derived from the amino acid L-methionine. It is characterized by the addition of a trifluoroacetyl group to the nitrogen atom of the methionine molecule. This modification enhances the reactivity and stability of the compound, making it useful in various chemical and biological applications. The trifluoroacetyl group imparts unique properties to the molecule, such as increased lipophilicity and resistance to hydrolysis, which can be beneficial in drug design and synthesis. L-Methionine, N-(trifluoroacetyl)- is often employed in peptide synthesis, where it can serve as a protecting group for the amino acid, preventing unwanted side reactions and ensuring the correct sequence of amino acids in the final peptide product.

2576-55-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2576-55-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,7 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2576-55:
(6*2)+(5*5)+(4*7)+(3*6)+(2*5)+(1*5)=98
98 % 10 = 8
So 2576-55-8 is a valid CAS Registry Number.
