Manufacturing Quality Control of 1-DIMETHYLAMINO-2-PROPYNE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent; endpoint detected amperometrically. |
| Residue on Evaporation | Gravimetric Analysis | Sample is evaporated to dryness under controlled temperature and pressure, and the non-volatile residue is weighed. |
| Acidity (as HCl) | Acid-Base Titration | Titration with standardized sodium hydroxide solution using phenolphthalein indicator to neutralize acidic impurities. |
| Alkalinity (as NaOH) | Acid-Base Titration | Titration with standardized hydrochloric acid solution using methyl red indicator to neutralize basic impurities. |
| Color | Visual Comparison or Spectrophotometry (APHA scale) | Comparison of sample color against platinum-cobalt standard solutions or measurement of absorbance at 430 nm. |
| Density | Digital Density Meter | Measurement of mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface using calibrated prism instrument at 20 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal content after acid digestion and chelation, based on absorption of characteristic wavelength radiation. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration using silver nitrate with silver electrode detection; endpoint determined from potential inflection. |
| Non-Volatile Matter | Gravimetric Analysis | Evaporation of a known volume at 105 C followed by drying and weighing of residual solids. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Semi-quantitative identification and relative quantification of volatile odor-active impurities via retention time and mass spectral matching. |
