Manufacturing Quality Control of 936250-20-3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., starting materials, degradants) via gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, EtOAc, MeOH) using gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by ignition at 700-800 C followed by precise weighing of residual residue. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against defined reference standards. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity by determining rotation angle of plane-polarized light in solution at specified concentration and wavelength. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample using Mie scattering theory to report D10, D50, D90 values. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determines pH of a standardized suspension (e.g., 1% w/v in water) using calibrated glass electrode and pH meter. |
