Manufacturing Quality Control of 4-(Cyanomethyl)benzeneboronic acid pinacol ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification relies on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Measures residual solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generated electrochemically in a methanol-based reagent. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe) by inductively coupled plasma mass spectrometry after acid digestion and dilution. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after charring and incineration at 600 C, followed by precise weighing of the ash. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of bulk sample against defined standards under controlled lighting and white background. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral centers in solution using sodium D-line (589 nm) at specified concentration and temperature. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using angular scattering pattern analysis of laser beam. |
| pH of Aqueous Slurry | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 10% w/v in water) using calibrated pH electrode and buffer reference standards. |
