Manufacturing Quality Control of 137529-41-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient HPLC-UV; identification supported by retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., toluene, heptane) using capillary GC with flame ionization detection and internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-free reagent system based on stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni, As) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution for high sensitivity and accuracy. |
| Chloride Content | Ion Chromatography | Measures chloride ion concentration using suppressed conductivity detection after separation on anion-exchange column with sodium carbonate/bicarbonate eluent. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated digital apparatus with controlled heating rate and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against defined standards (e.g., USP <901>). |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder using standardized graduated cylinder and calibrated balance. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using Mie theory-based scattering pattern analysis of laser beam passing through dispersed sample. |
| Sulfated Ash | Gravimetric Analysis | Quantifies inorganic residue after controlled combustion at 700-750 C followed by weighing of cooled crucible containing non-volatile sulfate salts. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light source and temperature-controlled cell to assess chiral purity and absence of racemization. |
