Manufacturing Quality Control of 4-(Methylthio)phenylboronic 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 structurally related impurities (e.g., 4-hydroxy-, 4-methyl-, or deboronated analogs) via gradient HPLC-UV with relative response factor correction. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, methanol, toluene) using headspace GC with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines trace water by electrochemical iodine generation and stoichiometric reaction with water in anhydrous solvent. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Quantifies elemental impurities at sub-ppb levels via inductively coupled plasma mass spectrometry after acid digestion and matrix-matched calibration. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature (700–800 °C) ashing of sample and precise weighing of the residue. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities affecting lattice integrity. |
| Appearance | Visual Inspection | Assesses physical state, color, and homogeneity against established reference standards under controlled lighting and viewing conditions. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Boron Content | ICP-OES | Verifies stoichiometric boron content by measuring total boron emission intensity at 249.773 nm following microwave-assisted alkaline digestion. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder using Mie scattering theory applied to laser light diffraction patterns. |
| pH of Aqueous Slurry | pH Meter | Determines acidity/basicity of saturated aqueous suspension (e.g., 1% w/v) using calibrated pH electrode in thermostatted medium. |
| Microbial Contamination | Membrane Filtration & Plate Count | Detects aerobic microorganisms by filtration, membrane transfer to nutrient agar, and colony enumeration after incubation per USP <61>. |
