Manufacturing Quality Control of 3-(Methylthio)phenylboronic 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 matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., methanol, THF, toluene) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| 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-ppb sensitivity. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against chloride standard calibration curve. |
| Sulfate Impurity | Ion Chromatography | Anion-exchange chromatography with suppressed conductivity detection to measure sulfate derived from oxidation or residual reagents. |
| Residue on Ignition | Gravimetric Analysis | Weight measurement of non-volatile inorganic residue after high-temperature ashing at 700-800 C in a muffle furnace. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against defined reference standards. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light by chiral compounds; used to detect enantiomeric impurities if applicable (though compound is achiral, confirms absence of chiral contaminants). |
| pH of Aqueous Suspension | pH Meter | Determination of acidity/basicity in 1% w/v suspension in water using calibrated pH electrode; indicates residual acidic/basic reagents or degradation products. |
