Manufacturing Quality Control of 2,6-Difluoro-4-hydroxybenzonitrile
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 220 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., starting materials, intermediates, degradants) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., acetonitrile, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol buffer. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic residue after controlled combustion at 700-800 C followed by weighing of the residual ash. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing the temperature range at which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized lighting and against white/black backgrounds. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size by measuring angular variation in intensity of laser light scattered by dispersed particles in liquid medium. |
| Organic Volatile Impurities (OVI) | GC-MS | Targeted and non-targeted screening of volatile and semi-volatile organic impurities using gas chromatography coupled with mass spectrometric detection. |
