Manufacturing Quality Control of 2-Bromoterephthalic acid
| 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 matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., acetone, toluene, DMF) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent; measures water via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion; detection based on element-specific atomic emission intensities in plasma. |
| Chloride Impurity | Ion Chromatography | Separation of anions on anion-exchange column with suppressed conductivity detection; quantifies chloride relative to calibration standards. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using controlled heating rate; onset and clear point recorded per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized white light and against specified reference standards. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying under controlled temperature and vacuum; reflects volatile content including residual moisture and solvents. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized NaOH solution using phenolphthalein indicator; expressed as mg KOH/g sample. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to determine volume-based particle size distribution in dispersed suspension. |
| Bulk Density | Tap Density Measurement | Determined by measuring mass of sample in a graduated cylinder before and after standardized mechanical tapping per USP <616>. |
