| Chemical Research | Used to construct libraries of complex heterocyclic compounds | Applied in multicomponent coupling and functional group transformation reactions |
| 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 to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., mono-chloro analogs, deboronated byproducts) via gradient HPLC-UV against qualified reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) using gas chromatography with flame ionization detection and external calibration. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration where iodine reacts stoichiometrically with water in a pyridine-methanol solvent system. |
| Heavy Metals (Total) | ICP-OES | Quantifies total elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Chloride Content | 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 at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dry dispersion mode based on angular dependence of laser light scattering. |
| Bulk Density | ASTM D1895 | Determines mass per unit volume of freely settled powder using standardized cylinder and funnel apparatus. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measures weight loss upon heating (105 C, 2 h) under nitrogen, reflecting volatile content including residual solvents and moisture. |
| 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 after equilibration. |
