Industrial Applications of 1,2,3,4-TETRA-O-ACETYL-BETA-D-XYLOPYRANOSE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Synthesis intermediate for antibiotic drugs | Serves as a key glycosyl donor in the formation of glycosidic bonds for synthesizing carbapenem antibiotics (e.g., the side chain of ertapenem) and other β-lactam antibiotics. |
| Pharmaceutical Industry | Synthesis of drug precursors | Used to synthesize drug molecules or prodrugs containing a xylose moiety, with acetyl groups serving as hydroxyl protecting groups that are subsequently removed after reaction completion. |
| Organic Synthesis | Glycochemical protecting group strategy | Acts as an activated xylose donor for introducing xylose units into complex carbohydrate synthesis; acetyl groups serve as general protecting groups removable via deprotection reactions upon reaction completion. |
| Scientific Research | Biochemical mechanism studies | Employed in enzymology research as a substrate or inhibitor to investigate the catalytic mechanisms and stereoselectivity of glycosidases, glycosyltransferases, and related enzymes. |
| Diagnostic Reagents | Raw material for diagnostic reagents | Used to synthesize specific carbohydrate derivatives as components of diagnostic reagents for detecting relevant metabolites or enzyme activity. |
Manufacturing Quality Control of 1,2,3,4-TETRA-O-ACETYL-BETA-D-XYLOPYRANOSE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on UV absorbance at ~205 nm using a reversed-phase C18 column and external standard calibration. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities (e.g., triacetyl, deacetylated, or epimeric forms) via gradient elution and peak area comparison. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual acetic anhydride, pyridine, dichloromethane, or methanol against certified standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, leveraging high sensitivity and isotopic resolution. |
| Optical Rotation | [α]D | Measurement of specific rotation at 589 nm (Na D-line) using a polarimeter to confirm stereochemical integrity and enantiomeric purity. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile inorganic residue after controlled ashing at 600–700 °C in a platinum crucible. |
| Acid Value | Potentiometric Titration | Titration with standardized KOH solution to quantify free carboxylic acid impurities (e.g., acetic acid) using pH endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary apparatus per USP <741>. |
