Manufacturing Quality Control of Methyl 2,3,4-Tri-O-acetyl-b-D-glucuronic Acid Methyl Ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 205-210 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., deacetylated, hydrolyzed, or isomeric forms) using gradient HPLC and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., acetone, methanol, ethyl acetate) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based reagent where water reacts stoichiometrically with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Quantifies toxic elements (Pb, Cd, Hg, As) by inductively coupled plasma mass spectrometry after acid digestion and dilution. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion with sulfuric acid treatment and high-temperature ignition to constant weight. |
| Optical Rotation | [alpha]D Measurement | Determines specific optical rotation using a polarimeter at 20-25 C and sodium D-line (589 nm) to confirm chiral integrity and identity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, confirming crystallinity and absence of significant impurities. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of substance against defined specifications (e.g., white to off-white crystalline powder). |
| pH of Solution | pH Meter | Measures hydrogen ion activity in aqueous solution (1% w/v) using calibrated pH electrode to detect acidic/basic degradation products. |
| Residual Catalyst (Pd) | ICP-OES | Quantifies palladium residues from catalytic hydrogenation steps using inductively coupled plasma optical emission spectrometry after microwave digestion. |
