Manufacturing Quality Control of 4'-CHLORO-4-BIPHENYLBORONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., residual aryl halides, boronic acid esters) via gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., THF, toluene, methanol) using capillary GC with flame ionization detection against external calibration standards. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol buffer. |
| Inorganic Chloride | Ion Chromatography (IC) | Measures chloride ion content after sample dissolution and filtration, using suppressed conductivity detection with sodium carbonate/bicarbonate eluent. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Quantifies trace heavy metals after microwave-assisted acid digestion, using inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Residual Palladium | ICP-OES | Measures palladium from cross-coupling catalyst residues after acid digestion, using inductively coupled plasma optical emission spectroscopy at characteristic wavelengths. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via comparison to literature value (138–140 C). |
| Loss on Drying (LOD) | Gravimetric Analysis | Measures weight loss after drying under controlled temperature and vacuum, reflecting volatile content including solvents and moisture. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against defined specifications (e.g., white to off-white crystalline powder). |
| pH of Aqueous Slurry | pH Meter | Measures hydrogen ion activity in a 1:10 w/v suspension in purified water, indicating acidic/basic impurities from synthesis or degradation. |
| Residual Boric Acid | Acid-Base Titration | Quantifies free boric acid by mannitol-enhanced titration with standardized NaOH, exploiting mannitol-induced acidity enhancement of boric acid. |
