Manufacturing Quality Control of 4-ETHYNYLBENZONITRILE 97
| 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 non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis | Sample is incinerated at 700-800 C, and the non-volatile inorganic residue is weighed after cooling in a desiccator. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of chloride anions on an anion-exchange column followed by conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion by measuring absorbance of ground-state atoms at characteristic wavelength. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color to APHA platinum-cobalt standard solutions or measurement of absorbance at 455 nm. |
| Relative Density | Digital Density Meter | Determination of density at 20 C by oscillating U-tube principle with temperature-controlled measurement. |
| Refractive Index | Abbe Refractometer | Measurement of light refraction angle at 20 C using sodium D-line (589 nm) to calculate refractive index. |
| Non-Volatile Residue | Gravimetric Evaporation | Evaporation of a known volume under controlled conditions followed by drying and weighing of residual matter. |
| Aldehyde Impurity | HPLC with UV Detection | Separation on reversed-phase column and quantification via UV absorbance at 270 nm relative to calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Sample treated with sulfuric acid, charred, ignited at 700 C, and residue weighed as sulfate ash. |
