Manufacturing Quality Control of 1-(5-Methyl-2-thienyl)ethan-1-one
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component using retention time and peak area against certified reference standard. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separates and detects impurities based on relative retention times and response factors. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvents are vaporized in sealed vials and quantified via GC-FID. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous medium. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions using visual match or UV-Vis absorbance at 455 nm. |
| Density | Digital Density Meter (Oscillating U-tube) | Measures sample density based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry (Abbe refractometer) | Determines refractive index by measuring critical angle of total internal reflection at prism-sample interface. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies metal content after acid digestion by measuring absorption of element-specific hollow cathode lamp radiation. |
| Sulfated Ash | Gravimetric Analysis (Ignition at 700 C) | Residue mass after high-temperature combustion of sample with sulfuric acid treatment is measured. |
| Chloride Content | Potentiometric Titration with AgNO3 | Silver nitrate reacts with chloride ions; endpoint detected by silver ion-selective electrode potential change. |
| Melting Point | Capillary Melting Point Apparatus | Temperature range at which solid transitions to liquid is observed visually or optically during controlled heating. |
