Manufacturing Quality Control of 3-PROPOXYPHENYLBORONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies 2-phenylimidazole peak area against a calibrated standard curve using UV detection at ~254 nm. |
| Related Substances | HPLC-UV | Separates and quantifies impurities (e.g., unreacted benzaldehyde, imidazole, dimers) relative to main peak using gradient elution. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., ethanol, toluene, DMF) by flame ionization detection after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (Pb, Cd, Hg, As, Ni) by mass spectrometric detection of elemental ions after acid digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride anions using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard reference. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration followed by precise weighing of residual residue. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to detect chiral impurities or enantiomeric excess (though compound is achiral, detects optically active contaminants). |
| pH of Aqueous Suspension | pH Meter | Determines acidity/basicity of saturated aqueous suspension using calibrated electrode, indicating acidic/basic impurities. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume after standardized tapping, indicating powder flow and handling characteristics. |
