Manufacturing Quality Control of 1-Methyl-1H-pyrazole-5-boronic 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 210-230 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., residual starting materials, de-borylated products) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Measures trace organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe) by inductively coupled plasma mass spectrometry after acid digestion and dilution. |
| Residual Boron | ICP-OES | Measures total boron content by inductively coupled plasma optical emission spectroscopy following microwave-assisted nitric acid digestion. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against defined reference standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Loss on Drying | Gravimetric Analysis | Measures volatile matter loss by weight difference before and after drying at 60 C under vacuum for 2 hours. |
| Residual Palladium | ICP-MS | Specific quantification of palladium catalyst residue using isotope-dilution ICP-MS after closed-vessel digestion. |
| pH of Aqueous Suspension | pH Meter | Measures pH of 1% w/v suspension in water using calibrated pH electrode, indicating acidic/basic decomposition products. |
