Manufacturing Quality Control of Undecanolactone
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity/Assay | Gas Chromatography (GC) | Separates sample components by gas chromatography and determines the content of the main component using area normalization or internal standard method to evaluate purity. |
| Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation capability of GC with the qualitative identification power of MS, enabling simultaneous qualitative and quantitative analysis for improved accuracy. | |
| Identification | Fourier Transform Infrared Spectroscopy (FTIR) | Confirms the structure of δ-undecalactone by identifying characteristic functional group absorption peaks (e.g., C=O, C–O). |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyzes chemical shifts and coupling constants of hydrogen atoms in the molecule to verify compound structure. | |
| Moisture Content | Karl Fischer Titration | A highly specific and sensitive method for moisture determination, suitable for trace water detection. |
| Acid Value | Acid-Base Titration | Titrates with standard potassium hydroxide ethanol solution using phenolphthalein as indicator to calculate free acid content. |
| Color | Visual Color Comparison or Colorimeter Method | Compares with standard color solutions, or uses a colorimeter to measure L*a*b* values for evaluating appearance quality. |
| Refractive Index | Abbe Refractometer Method | Measures refractive index at a specified temperature as an auxiliary parameter for identification and purity assessment. |
| Relative Density | Pycnometer Method or Digital Density Meter | Determines the density ratio of the sample to water at 20°C for quality consistency control. |
| Residual Solvents | Headspace-Gas Chromatography (HS-GC) | Suitable for detecting residual volatile organic solvents; offers high sensitivity and simple operation. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Detects levels of harmful elements such as lead, arsenic, mercury, and cadmium to ensure compliance with safety standards. |
