6919-98-8 Usage
Chemical structure
A derivative of β-D-glucopyranuronic acid, a sugar acid found in various polysaccharides, with three acetyl groups (-COCH3) at the 2, 3, and 4 positions, a bromine atom (Br) at the 1 position, and a methyl ester group (-OCH3) at the carboxylic acid group.
Functional groups
Acetyl groups (-COCH3), bromine atom (Br), and methyl ester group (-OCH3).
Molecular weight
Approximately 391.2 g/mol
Appearance
A white or off-white crystalline solid
Solubility
Soluble in organic solvents such as dichloromethane, chloroform, and acetone
Stability
Stable under normal laboratory conditions, but sensitive to moisture and heat
Reactivity
Reacts with nucleophiles, such as amines and alcohols, to form various glycosidic linkages
Synthesis
Prepared by acetylating the hydroxyl groups of β-D-glucopyranuronic acid, followed by bromination at the 1 position, and finally methylation of the carboxylic acid group
Applications
Used as an intermediate or building block in organic synthesis, particularly in the synthesis of carbohydrate-based pharmaceuticals, agrochemicals, and other bioactive compounds
Unique structure
The presence of the bromine atom and the methyl ester group allows for further functionalization and modification of the molecule, making it a versatile starting material for creating complex molecules
Safety precautions
Handle with care, as it may be harmful if inhaled, ingested, or if it comes into contact with the skin. Use appropriate personal protective equipment (PPE) and follow proper laboratory safety protocols.
Check Digit Verification of cas no
The CAS Registry Mumber 6919-98-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,1 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6919-98:
(6*6)+(5*9)+(4*1)+(3*9)+(2*9)+(1*8)=138
138 % 10 = 8
So 6919-98-8 is a valid CAS Registry Number.
