Manufacturing Quality Control of 4 - boric acid pinacol ester - 9, 9 - dimethyl fluorene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound using reversed-phase HPLC with UV detection at 254 nm based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities by comparing retention times and peak areas against reference standards or threshold responses. |
| Residual Solvents | GC-FID | Measures volatile organic solvents using gas chromatography with flame ionization detection and external calibration. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration where iodine reacts stoichiometrically with water in anhydrous medium. |
| Heavy Metals | ICP-MS | Quantifies trace metal elements (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| 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 high-temperature incineration followed by weight difference of the residue. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid sample against standard white background under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder using Mie scattering theory applied to laser light diffraction patterns. |
| Bulk Density | ASTM D1895 | Determines mass per unit volume of freely settled powder using standardized graduated cylinder and tapping procedure. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral compound in solution using sodium D-line at specified concentration and path length. |
