Manufacturing Quality Control of (1-Methyl-1H-pyrazol-5-yl)-boronic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities by gradient HPLC-UV; identification based on retention time relative to reference standards or threshold reporting. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., methanol, THF, ethyl acetate) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (Pb, Cd, Hg, As, etc.) after acid digestion, using inductively coupled plasma mass spectrometry for sub-pptr sensitivity. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration at 600-700 C, followed by precise weighing of residual residue. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity via comparison to literature value. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against defined specifications. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light through a solution, confirming chiral integrity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using light scattering pattern to determine D10, D50, D90 values per ISO 13320. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a standardized suspension (e.g., 1% w/v in water) using calibrated electrode to assess acidic/basic degradation products. |
