Manufacturing Quality Control of Penta-O-benzoyl-alpha-D-mannopyranose
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 230 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally similar impurities using gradient elution and UV detection; reported as individual and total impurities. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., acetone, ethyl acetate, toluene) based on retention time and peak area. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric electrochemical reaction. |
| Heavy Metals | ICP-MS | Inductively coupled plasma mass spectrometry for simultaneous quantification of elemental impurities (e.g., Pb, Cd, As, Hg) at sub-ppb levels. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against sodium chloride calibration standards. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 500-600 C followed by sulfuric acid treatment and final weighing of inorganic residue. |
| Optical Rotation | [alpha]D Measurement | Measurement of plane-polarized light rotation in solution at 20 C using sodium D-line (589 nm); confirms chiral integrity and identity. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, indicating purity and crystallinity. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to calculate volume-based particle size distribution in dry or dispersed state. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and absence testing for specified pathogens (e.g., E. coli, S. aureus) per USP <61> and <62>. |
| Residual Benzoyl Chloride | GC-MS | Gas chromatography coupled with mass spectrometry to detect and quantify unreacted benzoyl chloride based on molecular ion and fragment patterns. |
