Manufacturing Quality Control of ALPHA-D-GALACTURONIC ACID HYDRATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies carboxylic acid groups via neutralization with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint detection. |
| Loss on Drying (LOD) | Gravimetric Thermogravimetry | Measures mass loss after drying at 105 °C under controlled conditions to determine volatile content, including residual water and solvents. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Sulfated Ash Test | Determines inorganic impurities by incinerating sample with sulfuric acid followed by high-temperature ashing and weighing the residual sulfate salts. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals (expressed as lead) after wet digestion and measurement of absorbance at characteristic wavelengths. |
| Specific Optical Rotation | [α]D | Measures optical activity using a polarimeter at 20 °C with sodium D-line (589 nm) to confirm stereochemical identity and enantiomeric purity. |
| Related Substances (Impurities) | Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) | Separates and quantifies structurally related impurities (e.g., galactose, glucuronic acid, degradation products) using UV detection at 210 nm. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determines acidity/basicity of a 1% w/v aqueous solution using calibrated pH electrode in accordance with USP/EP general chapter. |
| Water Content | Karl Fischer Coulometric Titration | Quantifies trace water via electrochemical iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Microbial Limits | Membrane Filtration / Plate Count | Detects and enumerates aerobic mesophilic bacteria, yeasts, and molds per pharmacopoeial microbiological testing guidelines (e.g., USP <61>). |
