α-Methyl-p-nitrobenzyl-MBP bromide, also known as α-methyl-4-nitrobenzyl-6-methoxy-2-benzothiazolyl bromide, is a chemical compound with the molecular formula C15H13BrN2O3S. It is a derivative of 2-benzothiazolyl bromide, featuring a methyl group at the α-position, a nitro group at the para-position on the benzene ring, and a methoxy group at the 6-position. α-methyl-p-nitrobenzyl-MBP bromide is often used as a fluorescent labeling reagent in biochemistry and molecular biology due to its ability to react with amines, forming stable conjugates that can be detected under UV light. Its properties make it a valuable tool for studying protein-protein interactions, enzyme activity, and other biological processes.
The CAS Registry Mumber 83118-61-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,1 and 8 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 83118-61: (7*8)+(6*3)+(5*1)+(4*1)+(3*8)+(2*6)+(1*1)=120 120 % 10 = 0 So 83118-61-0 is a valid CAS Registry Number.
