Manufacturing Quality Control of 5-Methylquinoline
| 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 under optimized chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color to platinum-cobalt standard solutions using visual assessment or absorbance at 455 nm. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 degC | Refractometry (Abbe refractometer) | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Ignition at 600 degC) | Weighing of non-volatile residue remaining after high-temperature combustion of a weighed sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal content by measuring absorption of specific wavelength light by ground-state atoms in a flame or graphite furnace. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation and quantification of chloride anions using anion-exchange column and suppressed conductivity detection. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporation of a measured sample volume to dryness followed by weighing of residual solids. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and semi-quantitative assessment of structurally related impurities using retention time and mass spectral matching. |
| Boiling Range | Distillation (Micro or Semi-micro Method) | Determination of temperature interval over which 10% to 90% of the sample distills under controlled atmospheric pressure. |
