Manufacturing Quality Control of (S)-(-)-3-Butyn-2-ol
| 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. |
| Optical Rotation | [alpha]D measurement using polarimeter | Measures specific rotation at 20 C and sodium D-line to confirm chiral integrity and enantiomeric excess. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying water via iodine generation and stoichiometric reaction with sample moisture. |
| Residue on Ignition | Gravimetric analysis after high-temperature ashing | Measures non-volatile inorganic impurities as weight percent after combustion at 700-800 C. |
| Heavy Metals | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Simultaneously detects trace metal contaminants (e.g., Pb, Cd, Hg, As) by atomic emission intensity. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions based on retention time and conductivity response relative to calibration standards. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH and phenolphthalein indicator | Neutralizes acidic impurities; endpoint detected by color change, calculates acidity equivalent to acetic acid. |
| Color (APHA) | Visual comparison or spectrophotometric measurement at 455 nm | Compares sample color intensity to platinum-cobalt standard scale using calibrated colorimeter or visual comparator. |
| Distillation Range | Simple distillation with thermometer and graduated receiver | Determines boiling interval under specified pressure to assess volatility profile and presence of low/high boilers. |
| Specific Gravity | Digital density meter at 20 C | Measures mass per unit volume relative to water at standardized temperature for batch consistency and identity verification. |
| Non-Volatile Residue | Evaporation gravimetry at 105 C | Quantifies residue after solvent evaporation under controlled heating; indicates presence of high-boiling or polymeric impurities. |
| Related Substances | GC-MS (Gas Chromatography-Mass Spectrometry) | Separates and identifies structural analogs and degradation products via retention time and characteristic mass fragmentation patterns. |
