Manufacturing Quality Control of 3,5-Dibromobenzyl bromide
| 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. |
| Related Substances | Gas Chromatography (GC) with FID detection | Separation and quantification of impurities (e.g., monobromo, tribromo, dibenzyl ether derivatives) relative to main peak using calibrated response factors. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Detection and quantification of volatile solvents (e.g., toluene, dichloromethane) by equilibrium partitioning into headspace gas phase. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralization of acidic impurities (e.g., HBr, brominated acids) with standardized sodium hydroxide using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluation of yellowness intensity by matching sample absorbance at 455 nm to APHA platinum-cobalt standard scale. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube principle) | Determination of mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Digital Refractometer (Abbe principle) | Measurement of light bending angle at air-sample interface using calibrated prism and internal light source. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantification of total heavy metals following acid digestion and reduction, using hollow cathode lamp absorption at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on anion-exchange column and detection via suppressed conductivity measurement. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash method) | Weighing of inorganic residue remaining after high-temperature combustion in presence of sulfuric acid to convert organics to volatile species. |
| Melting Point | Capillary Melting Point Apparatus (Digital) | Determination of temperature range over which solid transitions to liquid, observed visually or optically through capillary tube heating. |
