Manufacturing Quality Control of 2-Bromofluorene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., fluorene, 1-bromofluorene, 2,7-dibromofluorene) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., toluene, DMF, THF) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content in the sample. |
| Acid Value | Acid-Base Titration | Titration with standardized sodium hydroxide solution using phenolphthalein indicator to quantify acidic impurities. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion and dilution, per USP <232>/<233>. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions after aqueous extraction and filtration. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of crystalline solid against specified criteria (white to off-white crystals). |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying under controlled temperature and vacuum conditions for fixed time. |
| Residue on Ignition | Sulfated Ash Test | Ignition of sample at 600-800 C followed by gravimetric determination of non-volatile inorganic residue. |
| Specific Optical Rotation | Polarimetry | Measurement of optical rotation using sodium D-line light source to confirm absence of chiral contamination (should be near zero). |
