Manufacturing Quality Control of 3-BROMOTHIOPHENE-2-CARBONYL CHLORIDE
| 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 under optimized chromatographic conditions. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a controlled anhydrous medium. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Separation and quantification of volatile organic solvents using headspace equilibrium and flame ionization detection. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., residual HCl, carboxylic acids) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantitative detection of chloride ions via conductivity detection after anion exchange chromatography. |
| Heavy Metals (Pb, Cd, Hg, Cr) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metals in high-temperature plasma, followed by element-specific emission intensity measurement. |
| Residual Thionyl Chloride | Gas Chromatography (GC) with TCD detection | Direct quantification of unreacted thionyl chloride based on thermal conductivity response relative to calibration standards. |
| Color | Visual Comparison against APHA Scale | Subjective assessment of sample color intensity in solution compared to standardized platinum-cobalt reference solutions. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed as the temperature range over which solid phase converts to liquid under controlled heating rate. |
| Organic Impurities (Related Substances) | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation of structurally similar compounds on a reversed-phase column and UV absorbance-based quantification at 254 nm. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the liquid sample. |
| Refractive Index | Abbe Refractometer | Determination of refractive index based on critical angle measurement of light passing from sample to prism interface at specified temperature. |
