Manufacturing Quality Control of 4-Bromophenylacetyl chloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and carrier gas. |
| 4-Bromoacetophenone Impurity | Gas Chromatography (GC) with FID detector | Separation and quantification of the hydrolysis by-product via retention time matching and calibration curve. |
| Benzyl Chloride Impurity | Gas Chromatography (GC) with FID detector | Detection and quantification of residual benzyl chloride as a common synthesis intermediate or degradation product. |
| Acetic Acid Impurity | Acid-Base Titration with NaOH | Neutralization of free acetic acid using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical generation of iodine to react stoichiometrically with water; endpoint detected by current change. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Heating sample at 700-800 C to volatilize organics, then weighing inorganic residue after cooling in desiccator. |
| Chloride Ion (as HCl) | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver electrode to detect endpoint via abrupt potential change from AgCl precipitation. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Atomization and excitation of metals in high-temperature plasma; quantification via element-specific emission wavelengths. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color intensity against platinum-cobalt standard solutions or absorbance measurement at specified wavelength. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 C | Abbe Refractometer | Determination of refractive index by measuring critical angle of total internal reflection at prism-sample interface. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Neutralization of acidic impurities (e.g., HCl, acetic acid) using standardized potassium hydroxide in alcoholic solvent and phenolphthalein indicator. |
