Manufacturing Quality Control of 3,3'-DIFLUOROBIPHENYL
| 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 generated in situ reacts 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 impurities after acid digestion by measuring absorbance of ground-state atoms at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of anions on an ion-exchange column followed by conductivity detection; chloride quantified via calibration curve. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually as solid-to-liquid phase change under controlled heating rate per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state and clarity against specified criteria (e.g., white to off-white crystalline powder, free from visible particulates). |
| Organic Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Volatile impurities partitioned into headspace are separated by GC and identified/quantified by MS detection. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Sulfated Ash | Gravimetric Analysis | Sample treated with sulfuric acid, ignited to constant weight, and residual inorganic sulfate salts are weighed. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase column; impurities detected at 254 nm and quantified relative to main peak using external standard method. |
| Bulk Density | Tap Density Measurement | Mass of sample divided by its volume after standardized tapping (ASTM D1895); reported as g/mL. |
