Manufacturing Quality Control of Pyridine methanesulfonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Pyrithione Methylsulfonate Content) | HPLC-UV | Quantifies active ingredient using reversed-phase chromatography with UV detection at 254 nm. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration with iodine-based reagent. |
| Residual Solvents (e.g., Methanol, Acetone) | GC-FID | Separates and quantifies volatile solvents using gas chromatography with flame ionization detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace metals via inductively coupled plasma mass spectrometry with isotopic resolution. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Related Substances (Impurities) | HPLC-DAD | Identifies and quantifies structurally related impurities using diode array detection. |
| pH of Aqueous Solution | Potentiometric Titration | Measures hydrogen ion activity using calibrated pH electrode in standardized suspension/dilution. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser light through dispersed sample. |
| Bulk Density | Tap Density Measurement | Calculates mass per unit volume after controlled tapping of a known mass in a graduated cylinder. |
| Loss on Drying | Gravimetric Analysis | Determines volatile content by weight loss after drying at specified temperature and time. |
| Microbial Contamination | Membrane Filtration | Quantifies viable aerobic microorganisms by filtration, membrane transfer, and colony enumeration on agar media. |
