Manufacturing Quality Control of 1-PENTYN-3-OL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by separation on capillary column and flame ionization detection relative to certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring atomic absorption at characteristic wavelength. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample at specified temperature using Abbe refractometer. |
| Flash Point | Closed Cup Pensky-Martens Tester | Determines lowest temperature at which vapors ignite under controlled heating and ignition source. |
| Distillation Range | Simple Distillation with Thermometer | Measures initial and final boiling points under atmospheric pressure using calibrated distillation apparatus. |
| Aldehyde Impurities | HPLC with UV Detection | Separates and quantifies aldehyde-related impurities using reverse-phase column and UV absorbance at 210 nm. |
