Manufacturing Quality Control of 4-CARBOXY-2-CHLOROPHENYLBORONIC 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, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., starting materials, dechlorinated or decarboxylated analogs) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Measures total elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Quantifies chloride ion released upon hydrolysis or present as salt impurity using suppressed conductivity detection. |
| pH of Aqueous Suspension | pH Meter | Measures pH of a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode to assess acidic functionality. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation of phase change. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration (600-800 C) and weighing of residual residue. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size via light scattering pattern generated by dispersed sample in air stream. |
| Bulk Density | Graduated Cylinder Method | Calculates mass per unit volume (g/mL) of freely settled powder in standardized cylinder under controlled conditions. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms (total viable count, yeast/mold) by filtration, membrane transfer to agar media, and colony enumeration. |
