Manufacturing Quality Control of PYRITHIOXIN DIHYDROCHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Pyrithione Acid Content) | Acid-Base Titration with NaOH standard solution | Quantifies pyrithione acid by neutralizing its carboxylic acid group using standardized sodium hydroxide and phenolphthalein or potentiometric endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS or ICP-OES after acid digestion | Measures trace metal concentrations via plasma-induced atomic emission or mass spectrometry following microwave-assisted nitric/hydrogen peroxide digestion. |
| Residual Solvents (e.g., Ethanol, Acetone) | Gas Chromatography (GC) with FID or HS-GC | Separates and quantifies volatile organic solvents using capillary column GC with flame ionization detection or headspace sampling. |
| Related Substances (Impurities) | Reverse-Phase HPLC with UV detection | Separates and detects structurally related impurities (e.g., unreacted precursors, degradation products) using C18 column and UV absorbance at 254 nm. |
| Water Content | Karl Fischer Coulometric Titration | Determines trace water by electrochemical generation of iodine and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures inorganic ash content by ignition at 700–800 °C followed by precise weighing of residual non-volatile matter. |
| pH of Aqueous Solution (1% w/v) | Potentiometric pH Measurement | Determines hydrogen ion activity in a standardized aqueous suspension using calibrated glass electrode and pH meter. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension by analyzing angular scattering pattern of laser light. |
| Microbial Limits (Total Aerobic Count, Yeast/Mold) | Membrane Filtration + Plate Count Agar Culture | Quantifies viable microorganisms by filtration, membrane transfer to selective media, and colony enumeration after incubation. |
| Specific Optical Rotation | [α]D at 20 °C | Measures chiral purity and identity via polarimetric detection of rotation angle of plane-polarized light passing through a standardized solution. |
| Melting Point | Capillary Melting Point Apparatus | Determines purity and identity by observing temperature range over which solid transitions to liquid under controlled heating. |
| Sulfate Residue | Barium Sulfate Gravimetric Method or Ion Chromatography | Quantifies sulfate as insoluble BaSO₄ precipitate after precipitation with barium chloride, or via anion-exchange separation and conductivity detection. |
| Chloride Content | Potentiometric Titration with AgNO₃ | Determines chloride ions by titration with silver nitrate using silver indicator electrode or adsorption indicator (e.g., potassium chromate). |
