Manufacturing Quality Control of 1-Benzyl-2-pyrrolidinone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as HCl) | Acid-Base Titration | Titration with standardized sodium hydroxide solution using phenolphthalein indicator to determine titratable acidic impurities. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to volatilize organic matter, then weighing the non-volatile inorganic residue. |
| Heavy Metals | ICP-OES | Multi-element detection after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantification of chloride ions using an anion-exchange column and conductivity detection. |
| Appearance | Visual Inspection | Comparison of liquid sample against water-white standard under controlled white light and specified viewing conditions. |
| Color (APHA) | Visual Colorimetry or Spectrophotometry | Comparison of sample color to APHA platinum-cobalt scale using matched glass cells or spectrophotometric absorbance at 430 nm. |
| Density | Digital Density Meter | Measurement of mass per unit volume at 20 C using oscillating U-tube principle with temperature-controlled sample cell. |
| Refractive Index | Refractometry | Determination of ratio of speed of light in air vs. sample at 20 C using total internal reflection principle. |
| Boiling Point | Distillation (Micro or Semi-micro) | Measurement of temperature at which vapor pressure equals atmospheric pressure during controlled distillation under reduced pressure if needed. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporation of fixed volume under nitrogen stream at 105 C, followed by weighing of residual solids. |
