Manufacturing Quality Control of 4,4,4',4',5,5,5',5'-octaethyl-2,2'-bi(1,3,2-dioxaborolane)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at characteristic wavelength based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities by retention time and UV response relative to main peak using validated gradient method. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents by gas chromatography with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in anhydrous methanol-based medium. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (e.g., Pd, Ni, Fe) after acid digestion by inductively coupled plasma mass spectrometry with isotope dilution quantification. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and precise weighing of the crucible residue. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube and controlled heating rate. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral compound in solution using sodium D-line light and standardized cell path length. |
| Bulk Density | USP <616> Tap Density Method | Determines mass per unit volume of powder after mechanical tapping in a graduated cylinder to achieve reproducible packing. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry or dispersed particles by analyzing angular scattering pattern of laser beam passing through sample. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determines hydrogen ion activity in saturated aqueous suspension using calibrated glass electrode and pH meter under controlled temperature. |
