21665-19-0 Usage
Sugar derivative
Contains a furanose ring
The compound is derived from a sugar (glucose) and features a furanose ring, which is a five-membered ring structure commonly found in carbohydrates.
Isopropylidene groups
Two isopropylidene groups are attached to the sugar ring
These groups are used to protect specific hydroxyl (-OH) functionalities in the molecule, preventing unwanted reactions at those sites.
Thiapropyl group
One thiapropyl group is attached to the sugar ring
This group is a sulfur-containing analog of a propyl group, which is also used as a protecting group for hydroxyl functionalities.
Protecting group
Commonly employed as a protecting group in carbohydrate chemistry
The compound serves as a temporary shield for hydroxyl groups, allowing for selective modification of the sugar molecule without affecting the protected sites.
Applications
Used in organic synthesis and carbohydrate biochemistry research
The compound is of interest in both organic chemistry and biochemistry, particularly in the study of carbohydrates and their interactions with other molecules.
Stereochemistry
alpha-D-glucopyranose
The compound has a specific stereochemistry, with the hydroxyl group at the C1 position being in the alpha configuration, and the sugar ring being in the pyranose form (a six-membered ring).
Solubility
Not explicitly mentioned in the material, but as a sugar derivative, it is likely soluble in polar solvents such as water and methanol.
Stability
The compound is stable under normal laboratory conditions, but it may be sensitive to acidic or basic conditions that could potentially remove the protecting groups.
Reactivity
The compound is relatively unreactive due to the presence of protecting groups, but it can undergo specific reactions to modify the sugar molecule at unshielded sites.
Check Digit Verification of cas no
The CAS Registry Mumber 21665-19-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,6 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21665-19:
(7*2)+(6*1)+(5*6)+(4*6)+(3*5)+(2*1)+(1*9)=100
100 % 10 = 0
So 21665-19-0 is a valid CAS Registry Number.
