Manufacturing Quality Control of 2-CHLOROPYRIMIDINE-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 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 by retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, heptane) by headspace GC with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine generated electrochemically or added reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, Ni, Pd) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing of the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against established reference standards. |
| Bulk Density | Tap Density Measurement | Measures mass per unit volume after standardized tapping (ASTM D1895) to assess powder flow and handling characteristics. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution in dry dispersion mode using Mie scattering theory and calibrated instrument. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode following equilibration. |
