Manufacturing Quality Control of 2-Nitrophenylboronic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase chromatography with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., nitrophenol isomers, boronic acid dimers) via gradient HPLC-UV against qualified impurity standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection using headspace sampling. |
| 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 medium. |
| Heavy Metals | ICP-OES | Quantifies elemental impurities (Pb, Cd, Hg, As, etc.) after microwave-assisted acid digestion, using plasma excitation and atomic emission detection. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion at 700-750 C in presence of sulfuric acid, followed by weighing of residual ash. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against defined specifications under standardized lighting and viewing conditions. |
| Loss on Drying | Thermogravimetric Analysis | Measures mass loss upon heating at 105 C for 2 hours, indicating volatile content including residual moisture and low-boiling impurities. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a 1% w/v suspension in CO2-free water using calibrated pH electrode and buffer standards. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of dry powder using Mie scattering theory applied to laser light diffraction patterns generated by dispersed particles. |
