Manufacturing Quality Control of HOMOPHTHALONITRILE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and carrier gas. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium, detecting endpoint potentiometrically. |
| Residue on Ignition | Gravimetric Analysis | Sample is incinerated at 700-800 C to oxidize organic matter; residual inorganic ash is weighed after cooling in a desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions by measuring absorption of characteristic wavelength light after atomization in a graphite furnace or flame. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of anions on an ion-exchange column followed by conductivity detection; chloride quantified via calibration curve. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator or potentiometric endpoint. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample solution color against APHA platinum-cobalt standard solutions or measurement of absorbance at 455 nm. |
| Specific Gravity | Digital Density Meter | Measurement of sample density relative to water at 20 C using oscillating U-tube principle with temperature-controlled cell. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface using calibrated prism and monochromatic sodium D-line (589 nm). |
| Volatility Residue | Thermogravimetric Analysis (TGA) | Mass loss measured under controlled nitrogen atmosphere from 25 C to 150 C; residue reported as weight percent. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase C18 column; impurities detected at 220 nm and quantified against reference standards or area normalization. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Hydrogen ion activity determined using calibrated glass electrode immersed in saturated aqueous solution of the compound. |
