Manufacturing Quality Control of 2,5-Difluorobenzyl bromide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 2,5-difluorobenzyl bromide peak area relative to a calibration curve using an internal or external standard. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separates and quantifies impurities (e.g., isomers, residual solvents, hydrolysis products) based on retention time and response factor. |
| Residual Solvents (e.g., dichloromethane, toluene) | Headspace Gas Chromatography (HS-GC) | Volatile solvents are equilibrated in headspace vial and quantified via GC-FID using calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Free HBr is neutralized with standardized sodium hydroxide solution using potentiometric or indicator endpoint detection. |
| Residue on Ignition | Gravimetric Analysis | Sample is ignited at 700-800 C; non-volatile residue is weighed after cooling in desiccator. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Acid-digested sample is nebulized into plasma; elemental emission intensities are measured and compared to calibration standards. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Chloride ions are separated on anion-exchange column and quantified by conductivity response relative to chloride standards. |
| Appearance | Visual Inspection | Sample is observed in a clear glass container under controlled white light against white/black background for color, clarity, and particulates. |
| Melting Point | Capillary Melting Point Determination | Solid sample is heated gradually in capillary tube; onset and completion of phase transition are recorded optically. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Sample density is calculated from the resonant frequency shift of a U-shaped glass tube filled with the liquid. |
| Refractive Index | Refractometry (Abbe refractometer) | Measured by determining the critical angle of total internal reflection of light passing through the liquid sample at specified temperature. |
