Manufacturing Quality Control of Phthalonitrile
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,2-dicyanobenzene by separation on a capillary column and flame ionization detection relative to a certified reference standard. |
| Water Content | Karl Fischer Titration | Determines water via coulometric or volumetric titration using iodine generated electrochemically or added stoichiometrically in a methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (550-600 C) and weighing of the cooled crucible. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomic absorption at characteristic wavelengths after acid digestion and matrix-matched calibration. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography (IC) | Separates and quantifies sulfate ions using anion-exchange column and suppressed conductivity detection. |
| Acid Value | Acid-Base Titration | Determines free acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid using calibrated digital apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against a white background under controlled lighting per ICH Q5C. |
| Organic Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Identifies and quantifies residual solvents by thermal equilibration in headspace vial followed by GC separation and mass spectral detection. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related impurities using reversed-phase C18 column and UV absorbance at 220 nm. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping of a known mass in a graduated cylinder per ASTM D1895. |
