Manufacturing Quality Control of 847818-79-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound using reversed-phase HPLC with UV detection at 210-230 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., starting materials, de-boronated analogs, isomers) via gradient HPLC-UV against reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) by headspace GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration followed by weight difference of crucible before/after ignition. |
| 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 homogeneity of solid sample against established reference standard under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dry powder mode using Mie theory-based light scattering analysis. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity (if applicable) by measuring angle of rotation of plane-polarized light at specified wavelength and concentration. |
| Boron Content | ICP-OES | Quantifies total boron after microwave-assisted alkaline digestion using inductively coupled plasma optical emission spectrometry. |
| pH of Aqueous Suspension | pH Meter | Measures pH of 1% w/v suspension in purified water using calibrated pH electrode per USP <791>. |
