Manufacturing Quality Control of 3-ETHYNYLPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 3-ethynylpyridine peak area relative to a calibrated standard curve using flame ionization detection. |
| Related Substances | Gas Chromatography (GC) with FID or GC-MS | Separates and detects impurities based on retention time and/or mass spectral identification. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine generated in situ from a reagent reacting stoichiometrically with water. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals | ICP-OES | Quantifies trace metal elements (e.g., Pb, Cd, Hg, As) by measuring atomic emission intensities after plasma atomization and excitation. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Acidity (as HCl) | Acid-Base Titration | Titrates acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of the sample against specified standards under controlled lighting. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Specific Optical Rotation | Polarimetry | Determines rotation angle of plane-polarized light induced by chiral components in solution. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling residual solvents by analyzing vapor phase above heated sample. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous suspension or solution using calibrated glass electrode. |
