Manufacturing Quality Control of HOTU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210-230 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold reporting. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., ethyl acetate, acetonitrile, DMF) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using isotopic detection for high sensitivity. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against sodium chloride standard. |
| Residual Cyanide | Spectrophotometric Method (Pyridine-Barbituric Acid) | Cyanide reacts with chloramine-T and pyridine-barbituric acid to form a colored complex measured at 578 nm. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Electrochemical measurement using calibrated glass electrode in a 1% w/v aqueous suspension. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically during controlled heating of solid sample in capillary tube. |
| Bulk Density | ASTM D1895 Method A | Mass per unit volume measured by pouring powder into calibrated cylinder and leveling without compaction. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as function of angle to determine size distribution of suspended particles. |
| Counterion (PF6-) Content | Ion Chromatography with Conductivity Detection | Quantification of hexafluorophosphate anion after extraction and separation on anion-exchange column. |
