Manufacturing Quality Control of 4-Aminophenylboronic acid pinacol ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common solvents (e.g., THF, toluene, methanol) against calibrated standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water; endpoint detected potentiometrically. |
| Heavy Metals | ICP-OES | Multi-element quantitative analysis after acid digestion; detection based on characteristic atomic emission spectra following plasma excitation. |
| Chloride Content | Ion Chromatography | Separation of anions on an ion-exchange column with conductivity detection; quantification via calibration curve using sodium chloride standard. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing at 700-800 C and subsequent weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, observed visually under controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and wavelength (589 nm). |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution in dispersed dry or wet sample. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Direct measurement using calibrated glass electrode in a defined suspension (e.g., 10 mg/mL in water), reporting equilibrium pH value. |
| Microbial Limits | Membrane Filtration and Plate Count | Enumeration of aerobic microorganisms via filtration, membrane transfer to appropriate agar media, incubation, and colony counting per USP <61>. |
