Manufacturing Quality Control of 4-Propylbenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Related Substances | HPLC with UV detection | Separation and quantification of impurities by retention time and response relative to the main peak. |
| Residual Solvents | Gas Chromatography (GC) with FID | Volatiles are separated on a capillary column and detected via flame ionization; quantified against calibration standards. |
| Water Content | Karl Fischer titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent. |
| Heavy Metals | ICP-OES | Multi-element detection after acid digestion, based on characteristic atomic emission spectra intensities. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of anions on an ion-exchange column followed by conductivity detection. |
| Sulfated Ash | Gravimetric analysis | Sample incinerated at 700-800 C, residue treated with sulfuric acid and re-ignited; mass of residual inorganic salts measured. |
| Melting Point | Capillary melting point apparatus | Thermal transition observed visually as the temperature range over which solid transforms to liquid. |
| Appearance | Visual inspection | Assessment of physical state, color, and presence of foreign particles under controlled lighting conditions. |
| Acid Value | Acid-base titration with NaOH | Neutralization of carboxylic acid groups using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Loss on Drying | Thermogravimetric analysis (TGA) or oven drying | Mass loss measured after heating under specified temperature and time to remove volatile components. |
| Particle Size Distribution | Laser diffraction | Analysis of light scattering pattern from suspended particles to determine size distribution profile. |
