Manufacturing Quality Control of Benzo-15-crown-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 220 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient HPLC-UV; identification by retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., toluene, THF) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol medium. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion by inductively coupled plasma mass spectrometry with isotopic detection. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion at 700 C in presence of sulfuric acid, followed by weighing of residual ash. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube under controlled heating rate. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation of chiral impurities or enantiomeric excess using sodium D-line light in a polarimeter with standardized path length and concentration. |
| Loss on Drying | Thermogravimetric Analysis | Quantifies volatile loss (moisture, solvents) by measuring weight change upon heating to 105 C under nitrogen or air. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines acidity/basicity of saturated aqueous suspension using calibrated glass electrode and pH meter. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension using Mie scattering theory and laser diffraction pattern analysis. |
