Manufacturing Quality Control of 2-Acetylfluorene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally similar impurities using gradient HPLC with UV detection; identification and quantification relative to main peak. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., toluene, acetone) based on retention time and peak area calibration. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generation in pyridine-methanol buffer; water content determined by stoichiometric reaction with Karl Fischer reagent. |
| Heavy Metals | ICP-OES | Digestion followed by inductively coupled plasma optical emission spectrometry to measure trace metal concentrations (e.g., Pb, Cd, Hg, As) via element-specific atomic emission lines. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on an anion-exchange column with conductivity detection; quantified using external calibration standards. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature at which solid phase converts to liquid under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of sample against specified criteria (e.g., white to off-white crystalline powder, free from visible particulates). |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized potassium hydroxide solution using phenolphthalein indicator; calculated as mg KOH per g sample. |
| Sulfated Ash | Gravimetric Analysis | High-temperature incineration of sample followed by sulfuric acid treatment and final ash weighing to determine inorganic residue content. |
| Bulk Density | Tap Density Measurement | Mass of sample divided by its volume after controlled tapping in a graduated cylinder per USP <616>. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate size distribution based on Mie theory for dry or dispersed samples. |
