Manufacturing Quality Control of 4-BroMo-9,9-diMethyl fluorene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold reporting. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., toluene, acetone, methanol) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element trace metal analysis after acid digestion; quantification via atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; chloride quantified against calibration standards. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after controlled high-temperature ashing (700-800 C) to assess inorganic ash content. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, observed visually through capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference (e.g., white to off-white crystalline powder, free from visible particulates). |
| Bulk Density | Tap Density Measurement | Mass per unit volume measured after standardized tapping of a known mass in a graduated cylinder per USP <616>. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volumetric particle size distribution in dispersed phase. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution to confirm chiral purity and absence of racemization. |
