Manufacturing Quality Control of 2-Naphthoyl chloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 2-naphthoyl chloride peak area relative to a calibrated standard curve. |
| Acid Value | Acid-base titration with NaOH standard solution | Measures free acid content by neutralizing acidic impurities with standardized sodium hydroxide. |
| Moisture Content | Karl Fischer titration | Determines water content via coulometric or volumetric reaction between water and Karl Fischer reagent. |
| Residue on Ignition | Gravimetric analysis after high-temperature ashing | Measures non-volatile inorganic residue remaining after combustion at 700-800 C. |
| Chloride Content | Potentiometric titration with AgNO3 | Quantifies total chloride ions by silver nitrate titration using silver indicator electrode. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures trace heavy metal concentration by atomic absorption of characteristic wavelength light. |
| Color (APHA) | Visual comparison or spectrophotometric measurement at 455 nm | Evaluates yellowness intensity by comparing sample absorbance to platinum-cobalt standard scale. |
| Density at 20 C | Oscillating U-tube densitometry | Determines mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 C | Abbe refractometry | Measures bending of light passing through sample to determine optical density relative to air. |
| Non-Volatile Residue | Gravimetric analysis after solvent evaporation | Quantifies residue left after complete evaporation of volatile components under controlled heating. |
| Related Substances (Impurities) | High Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV absorbance. |
| Free Thionyl Chloride | Titration with dimethylformamide followed by hydrolysis and back-titration | Detects residual SOCl2 by conversion to HCl, then titration with standardized NaOH. |
