Manufacturing Quality Control of D-Mannosamine hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (D-Mannosamine Hydrochloride) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH using mixed indicator. |
| Water Content | Karl Fischer Titration | Measures water via iodometric reaction with Karl Fischer reagent in anhydrous methanol. |
| Specific Optical Rotation | Polarimetry | Determines enantiomeric purity by measuring rotation of plane-polarized light at specified wavelength and temperature. |
| pH (1% aqueous solution) | pH Meter Measurement | Evaluates acidity using calibrated pH electrode in a defined aqueous solution. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion with sulfuric acid treatment and ignition. |
| Chloride Impurity | Potentiometric Titration | Detects chloride ions via silver nitrate titration with silver electrode endpoint detection. |
| Related Substances | High Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally similar impurities using reversed-phase C18 column and UV detection. |
| Residual Solvents | Gas Chromatography (GC) | Identifies and quantifies volatile organic solvents using headspace GC with FID detection. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution based on angular variation of scattered laser light intensity. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized mechanical tapping of a powder sample. |
