Manufacturing Quality Control of Bis(4-cyanophenyl)methanol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching with reference standards. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, THF) against calibrated standards. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Quantification of trace metal impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 750 C followed by sulfuric acid treatment and final weighing of residual inorganic ash. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against specified criteria under controlled lighting conditions. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to determine D10, D50, D90 values. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a 1% w/v suspension in purified water using calibrated pH electrode. |
| Organic Volatile Impurities (OVI) | GC-MS | Targeted and non-targeted screening of residual process-related organics using gas chromatography-mass spectrometry with method-specific validation. |
