Benzyl 1-bromo-1-deoxy-2,3,4-tri-O-benzyl-D-glucopyranuronate is a complex organic compound with the molecular formula C31H31BrO5. It is a derivative of D-glucopyranuronic acid, a component of certain polysaccharides, with a bromine atom replacing the hydroxyl group at the first carbon position. The compound features three benzyl groups attached to the second, third, and fourth carbon atoms, which protect the hydroxyl groups and increase its solubility in organic solvents. This chemical is often used in organic synthesis, particularly in the preparation of complex carbohydrates and glycoconjugates, due to its ability to serve as a building block for more intricate molecular structures. Its protected nature allows for selective reactions at specific sites, making it a valuable intermediate in the synthesis of biologically active compounds.
The CAS Registry Mumber 4356-86-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,5 and 6 respectively; the second part has 2 digits, 8 and 6 respectively. Calculate Digit Verification of CAS Registry Number 4356-86: (6*4)+(5*3)+(4*5)+(3*6)+(2*8)+(1*6)=99 99 % 10 = 9 So 4356-86-9 is a valid CAS Registry Number.
