Benzyl 2,3,4-tri-O-acetyl-1-thio-β-D-xylopyranoside is a complex organic compound with the molecular formula C18H22O7S. It is a derivative of β-D-xylopyranoside, a monosaccharide sugar, where the hydroxyl group at the first carbon has been replaced by a thiol group, and the hydroxyl groups at the second, third, and fourth carbons are acetylated. benzyl 2,3,4-tri-O-acetyl-1-thio-β-D-xylopyranoside is often used in organic synthesis, particularly in the preparation of various glycosides and as a building block for more complex carbohydrates. It is also employed in the study of carbohydrate chemistry and as a potential intermediate in the synthesis of pharmaceuticals and other bioactive compounds. The benzyl group provides protection for the thiol group, which can be removed under specific conditions to reveal the free thiol, making it a versatile intermediate in chemical reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 2771-54-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,7 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2771-54:
(6*2)+(5*7)+(4*7)+(3*1)+(2*5)+(1*4)=92
92 % 10 = 2
So 2771-54-2 is a valid CAS Registry Number.

THE ACTION OF THIOLS ON DERIVATIVES OF D-XYLOSE

Blumberg, Karl,Es, Theodorus van

, p. 253 - 266 (2007/10/02)

The action of thiols on 1,2,3,4-tetra-O-acetyl β-D-xylopyranose gave 2- and 5-alkylthiopentose dithioacetals and alkyl 1-thio-D-xylopyranosides.On treatment with thiols and trifluoroacetic acid, 3-O-acetyl-1,2-O-isopropylidene-α-D-xylofuranose derivatives rapidly formed 4-O-acetyl-2,3-dialkylthio-D-ribose dithioacetal derivatives, which were in turn converted into 4-O-acetyl-3-S-benzyl-2,5-epithio-3-thio-D-ribose (or D-arabinose) dithioacetal.
