4-Imidazolidinemethanesulfonyl chloride, 4-methyl-2,5-dioxo-, (4S)-, also known as MTSET, is a chemical compound with the molecular formula C5H8ClN3O3S. It is a chiral, water-soluble reagent used in biochemistry and molecular biology for the specific modification of cysteine residues in proteins. MTSET is a methanesulfonate ester derivative of 1,2,4-oxadiazole-3-one, which is a highly reactive electrophile. It is commonly used to study the function of ion channels, receptors, and other proteins containing cysteine residues by covalently modifying them, leading to changes in their activity or conformation. The (4S)-enantiomer is the biologically active form, making it a valuable tool in the investigation of protein structure and function.

459818-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 459818-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,9,8,1 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.Calculate Digit Verification of CAS Registry Number 459818-50:
(8*4)+(7*5)+(6*9)+(5*8)+(4*1)+(3*8)+(2*5)+(1*0)=199
199 % 10 = 9
So 459818-50-9 is a valid CAS Registry Number.
