Manufacturing Quality Control of 1,1-bis(4-METHOXYPHENYL)-2-PROPYN-1-OL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient HPLC-UV; identification relies on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., methanol, THF, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based redox reaction in anhydrous pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Measures total elemental impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion by optical emission spectroscopy at characteristic wavelengths. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on an anion-exchange column with carbonate/bicarbonate eluent. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled combustion at 700-800 C followed by precise weighing of the ash. |
| Optical Rotation | [alpha]D Measurement | Determines specific rotation using a polarimeter at 20 C with sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against standard references under controlled white light and specified viewing conditions. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension by analyzing angular variation in laser light scattering intensity. |
