Manufacturing Quality Control of 1-PHENYL-3-CHLORO-1-PROPYNE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Chloride Impurities | Ion Chromatography (IC) | Separates and quantifies chloride ions using ion-exchange column and conductivity detection. |
| Heavy Metals | ICP-OES | Detects trace metal contaminants (e.g., Pb, Cd, Hg) by atomic emission spectroscopy after acid digestion. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | Visual Comparison or APHA Color Scale | Evaluates color intensity by comparing sample against platinum-cobalt standard solutions. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through sample to assess purity and concentration based on Snell's law. |
| Non-Volatile Residue | Gravimetric Evaporation | Quantifies residue after controlled evaporation of fixed sample volume under inert atmosphere. |
| Organic Volatile Impurities | Headspace GC-MS | Identifies and quantifies residual solvents and low-boiling impurities using thermal desorption and mass spectral detection. |
| Stability (Thermal Decomposition Onset) | Differential Scanning Calorimetry (DSC) | Detects exothermic decomposition events by measuring heat flow difference during controlled heating. |
