(2S,3R,4R,5R)-3,5-Bis-hydroxymethyl-tetrahydro-furan-2,3,4-triol is a complex organic compound with a unique molecular structure. It is a chiral molecule, meaning it has a non-superimposable mirror image, and is characterized by its specific stereochemistry, with the 2S, 3R, 4R, and 5R configurations indicating the arrangement of atoms in three-dimensional space. (2S,3R,4R,5R)-3,5-Bis-hydroxymethyl-tetrahydro-furan-2,3,4-triol features a tetrahydrofuran ring, which is a saturated heterocyclic structure with an oxygen atom in the ring, and contains three hydroxyl groups (-OH) at the 2, 3, and 4 positions, as well as two hydroxymethyl groups (-CH2OH) at the 3 and 5 positions. These functional groups give the molecule its distinct chemical properties and reactivity. The compound may have applications in the synthesis of various organic compounds and could be relevant in the fields of pharmaceuticals, chemical research, and material science.

Check Digit Verification of cas no

The CAS Registry Mumber 469-33-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 469-33:
(5*4)+(4*6)+(3*9)+(2*3)+(1*3)=80
80 % 10 = 0
So 469-33-0 is a valid CAS Registry Number.

Tannins and Related Compounds. XVII. Galloylhamameloses from Castanea crenata L. and Sanguisorba officinalis L.

Nonaka, Gen-ichiro,Ishimaru, Kanji,Tanaka, Takashi,Nishioka, Itsuo

, p. 483 - 489 (2007/10/02)

Together with 2',5-di-O-galloylhamamelose (I), which had previously been designated as hamamelitannin, five new galloylhamameloses (II-VI) were isolated from the bark of Castanea crenata L. (Fagaceae).On the basis of chemical and spectroscopic evidence, their structures were characterized as 2',3,5,tri-O-galloyl- (II), 5-O-galloyl- (III), 1,2'-di-O-galloyl-(IV), 1,2',5-tri-O-galloyl-(V) and 1,2',3,5-tetra-O-galloyl-D-hamamelofuranose (VI).In addition, the occurance of two galloylhamameloses (I and II) in the underground part of Sanguisorba officinalis L. (Rosaceae) was demonstrated.Keywords - Castanea crenata; Fagaceae; Sanguisorba officinalis; Rosaceae; galloylhamamelose; tannin; deutrium-induced differential isotope shift, 13C-NMR; 1H-NMR
