| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210-230 nm based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., cis-isomer, deboronated by-products, residual starting materials) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection against calibrated standards. |
| 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 | Quantifies elemental impurities (e.g., Pd, Ni, Cu) by inductively coupled plasma mass spectrometry after acid digestion. |
| Residual Palladium | ICP-OES | Measures palladium catalyst residue by inductively coupled plasma optical emission spectroscopy following microwave-assisted digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Acid Value | Acid-Base Titration | Determines free acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid or solution against established reference standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of phase transition using calibrated capillary apparatus per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity and identity via rotation of plane-polarized light at specified wavelength and concentration. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic residue after high-temperature ashing and weighing of the ignited sample. |
