Manufacturing Quality Control of 4-PHENOXYPHENYLBORONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold reporting. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., THF, toluene, methanol) against calibration standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppq sensitivity. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing (500-600 C) and weighing of the cooled crucible. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection, calibrated with NaCl standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using controlled heating and visual observation of crystal collapse. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against defined reference standards. |
| Bulk Density | ASTM D1895 | Measurement of mass per unit volume of freely settled powder using a calibrated cylinder and balance per ASTM standard method. |
| Particle Size Distribution | Laser Diffraction | Analysis of size distribution by measuring angular variation in laser light scattering from dispersed particles in air or liquid medium. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode after equilibration. |
