Manufacturing Quality Control of 135540-11-3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210–230 nm, comparing peak area against certified reference standard. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., acetonitrile, dichloromethane) via capillary GC with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemically determines trace water by iodine generation and stoichiometric reaction with water in anhydrous methanol-based electrolyte. |
| Inorganic Anions (Cl⁻, PO₄³⁻, F⁻) | Ion Chromatography (IC) | Separates and quantifies anionic impurities using suppressed conductivity detection after eluent gradient separation on anion-exchange column. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace metal impurities at sub-ppt levels by plasma ionization and mass-selective detection following acid digestion and dilution. |
| Residual Catalyst Metals (e.g., Pd, Ni) | ICP-OES | Quantifies transition metal residues via high-temperature plasma excitation and element-specific optical emission measurement. |
| Organic Impurities (Related Substances) | HPLC-UV/DAD | Identifies and quantifies structurally related degradation products and synthesis intermediates using gradient HPLC with diode array detection. |
| Particle Size Distribution | Laser Diffraction | Measures dry powder particle size distribution based on angular variation of laser light scattering intensity. |
| Bulk Density & Tapped Density | ASTM D6393 (Gravimetric Volumetric Method) | Determines density by measuring mass per unit volume before and after standardized mechanical tapping of a powder sample. |
| pH of Aqueous Suspension (1% w/v) | Potentiometric pH Measurement | Measures hydrogen ion activity in aqueous suspension using calibrated glass electrode and reference electrode system. |
| Melting Point | DSC (Differential Scanning Calorimetry) | Determines thermal transition temperature and enthalpy by monitoring heat flow difference between sample and reference during controlled heating. |
| Residual Pyridine/Pyrolidine Derivatives | GC-MS | Identifies and quantifies volatile amine impurities using gas chromatographic separation coupled with mass spectrometric detection and selected ion monitoring. |
| Counterion (PF₆⁻) Content | Ion-Pairing HPLC-UV or IC | Quantifies hexafluorophosphate anion either via ion-pairing RP-HPLC with UV detection after derivatization or direct IC with conductivity detection. |
| Microbial Limits | Membrane Filtration + Culture Enumeration | Detects aerobic microorganisms by filtration, membrane transfer to nutrient agar, and colony enumeration after incubation per USP <61>. |
