Manufacturing Quality Control of Cyclobutanecarboxylic acid, 3-methylene-, ethyl ester (9CI)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component using retention time and peak area calibration against reference standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents by equilibrium partitioning into headspace followed by GC separation. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines water via electrochemical iodine generation and stoichiometric reaction with water. |
| Acid Value | Acid-Base Titration (NaOH in ethanol) | Measures free carboxylic acid groups by titration with standardized sodium hydroxide solution. |
| Color | Visual Comparison or Hazen (APHA) Scale | Evaluates color intensity by comparing sample solution to platinum-cobalt standards under controlled lighting. |
| Density | Digital Density Meter (Oscillating U-tube) | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry (Abbe type) | Measures refractive index using critical angle of total internal reflection at prism-sample interface. |
| Chiral Purity | Chiral Gas Chromatography (Chiral GC) | Assesses enantiomeric excess using chiral stationary phase to separate enantiomers. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies metal impurities by measuring element-specific atomic emission after plasma atomization. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Determines residue after solvent evaporation under controlled temperature and vacuum, then weighing. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity using calibrated glass electrode in aqueous dispersion or saturated solution. |
