Manufacturing Quality Control of 4-ETHYNYLPHENYLACETONITRILE 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 calibrated column and detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent, measuring endpoint current or potential. |
| Residue on Ignition | Gravimetric Analysis | Sample is incinerated at 700-800 C, cooled in a desiccator, and weighed to determine non-volatile inorganic residue mass. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion by measuring absorption of characteristic wavelength light by ground-state atoms in a flame or graphite furnace. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of anions on an ion-exchange column followed by conductivity detection to quantify chloride concentration relative to standards. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator; calculated as mg KOH per g sample. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness intensity by matching sample color to APHA platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Relative Density | Digital Density Meter | Determination of density at 20 C by oscillating U-tube principle, comparing sample frequency response to calibration standards. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface using a calibrated prism, reported at 20 C and sodium D-line wavelength. |
| Non-Volatile Residue | Evaporation and Gravimetry | Sample is evaporated to dryness under controlled conditions, residue dried to constant weight, and mass determined gravimetrically. |
| Aldehyde Impurity | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by electron ionization and mass spectral identification/quantification using characteristic fragment ions. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Equilibration of sample in sealed vial, injection of headspace vapor into GC-FID for separation and quantification of volatile organic solvents. |
