Manufacturing Quality Control of Undecenoic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Assay | Gas Chromatography (GC) | Using a gas chromatograph with an internal or external standard method, the methyl ester derivative of undecylenic acid is separated on a capillary column and detected by a flame ionization detector (FID) to quantify its content. Sample requires methylation pretreatment. |
| High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column and a UV detector (typically at 200–210 nm), with acetonitrile-water or methanol-water as the mobile phase, to directly determine undecylenic acid content; suitable for non-volatile or thermally unstable samples. | |
| Purity Analysis | Gas Chromatography (GC) | Evaluates the purity of undecylenic acid by calculating the percentage area of the main peak in GC; can simultaneously detect residual solvents and impurity peaks. |
| Impurity Detection | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation capability of GC with the qualitative power of MS to identify organic impurities, isomers, or degradation products in undecylenic acid. |
| Thin-Layer Chromatography (TLC) | Uses silica gel plates and appropriate developing solvents (e.g., petroleum ether:ethyl acetate); spots are visualized after development to perform preliminary checks for impurities and purity. | |
| Acid Value | Acid-Base Titration | Titration with standardized ethanolic sodium hydroxide solution using phenolphthalein as indicator; acid value (mg KOH/g) is calculated to reflect free acid content. |
| Peroxide Value | Iodometric Method | Peroxides in the sample react with potassium iodide to liberate iodine, which is then titrated with standardized sodium thiosulfate solution. The peroxide value is calculated to assess the degree of oxidation. |
| Moisture Content | Karl Fischer Titration | Electrochemical reaction-based method for quantitative determination of moisture in samples; suitable for trace moisture analysis with high accuracy. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, measures residual levels of heavy metals such as lead, arsenic, mercury, and cadmium to ensure compliance with pharmacopoeial or safety standards. |
| Residual Solvents | Gas Chromatography (GC) | Determines organic solvents possibly remaining from manufacturing processes using headspace sampling-GC according to pharmacopoeial methods (e.g., Chinese Pharmacopoeia, USP). |
