Butanoic acid, 3-[(carboxymethyl)thio]-, also known as S-methyl methanethiosulfonate (MMTS), is a chemical compound with the molecular formula C5H10O4S2. It is a colorless, odorless, and crystalline solid that is soluble in water and various organic solvents. MMTS is widely used as a thiol-specific reagent in biochemistry and molecular biology, particularly for the reversible modification of cysteine residues in proteins. This modification allows for the study of protein structure, function, and interactions. Additionally, MMTS has applications in the synthesis of other organic compounds and as a reagent in various chemical reactions. Due to its reactivity with thiols, it is essential to handle MMTS with care and in a controlled environment to prevent unwanted side reactions.

4386-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4386-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,8 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.Calculate Digit Verification of CAS Registry Number 4386-05:
(6*4)+(5*3)+(4*8)+(3*6)+(2*0)+(1*5)=94
94 % 10 = 4
So 4386-05-4 is a valid CAS Registry Number.
