Manufacturing Quality Control of 1-HYDROXYMETHYL-3-CYCLOPENTENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness intensity by matching sample color to APHA platinum-cobalt scale or measuring absorbance. |
| Density at 20 degC | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 degC | Refractometry | Measures bending of light through liquid sample to infer purity and composition based on Snell's law. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume to dryness and weighs non-volatile residue after drying at 105 degC. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal content by measuring absorption of characteristic wavelength light by ground-state atoms in flame. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration monitored by silver electrode potential change. |
| Aldehyde Impurities | HPLC with UV Detection | Separates and quantifies aldehyde-related impurities using reversed-phase column and UV absorbance at 210 nm. |
| Peroxide Value | Iodometric Titration | Measures peroxides by oxidation of iodide to iodine under acidic conditions, followed by thiosulfate titration. |
| Non-Volatile Matter | Gravimetric Analysis | Determines insoluble particulates by filtration, drying, and weighing of retained residue on pre-weighed membrane filter. |
