Manufacturing Quality Control of 4-Bromophenetole
| 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 using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis | Sample is incinerated at 700-800 C, and the non-volatile inorganic residue is weighed after cooling in a desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion and chelation, based on absorption of characteristic wavelength light by ground-state atoms in flame. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of anions on an ion-exchange column followed by conductivity detection; chloride quantified via calibration curve. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator; calculated as mg KOH per g sample. |
| Color | Visual Comparison (APHA Scale) | Comparison of sample solution color against platinum-cobalt standard solutions under controlled lighting conditions. |
| Density | Digital Density Meter (Oscillating U-tube) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index | Refractometry (Abbe refractometer) | Determination of refractive index from the critical angle of total internal reflection at the prism-sample interface. |
| Non-Volatile Residue | Gravimetric Evaporation | Sample is evaporated to dryness at 105 C, cooled, and residual mass is measured gravimetrically. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and UV absorbance at 220-280 nm. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition temperature range using calibrated capillary tube method per USP <741>. |
