Manufacturing Quality Control of 5-Chloro-1-pentyne
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity Analysis | Gas Chromatography (GC) | Separates sample components using a capillary column, with FID detector for quantitative determination of the main component's purity; suitable for volatile organic compounds, with high sensitivity and good repeatability. Can be combined with internal standard method to improve accuracy. |
| Impurity Identification and Quantification | GC-MS (Gas Chromatography-Mass Spectrometry) | Combines the separation capability of GC with the structural identification ability of MS to identify and quantify by-products or degradation products (such as isomers, chlorinated by-products, oxidation products, etc.). |
| Moisture Determination | Karl Fischer Titration (KF Method) | Determines trace moisture through a quantitative reaction between iodine and sulfur dioxide in a pyridine/methanol system, with endpoint detection via potentiometric titration. Accurately measures moisture content to avoid affecting product stability. |
| Residual Solvent Detection | Headspace Gas Chromatography (HS-GC) | Sample is sealed and heated, then headspace gas is injected into GC for analysis; suitable for detecting residual volatile organic solvents (such as dichloromethane, ethyl acetate, toluene, etc.). |
| Appearance and Physical Properties | Visual Inspection / Refractive Index / Density Measurement | Visually inspect color and clarity; measure refractive index with a refractometer and density with a densimeter or pycnometer, used as preliminary quality assessment criteria. |
| pH Value (Acid-Base Degree) | pH Meter Measurement (After Aqueous Extraction) | Dissolve the sample in an appropriate amount of water or buffer solution, then measure the pH of the aqueous phase to assess whether acidic or basic impurities are present (e.g., residual HCl). |
| Elemental Analysis (Chlorine Content) | Combustion Method + Ion Chromatography / Potentiometric Titration | Converts organic chlorine into inorganic chloride ions through bomb combustion, then quantifies total chlorine content using ion chromatography or silver nitrate titration, verifying molecular composition consistency. |
