Manufacturing Quality Control of Dimethyl 2-bromoterephthalate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities by HPLC coupled with diode-array detection; peak purity and relative retention time comparison. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., methanol, dichloromethane) based on calibrated response factors. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 700-800 C followed by weighing of non-volatile inorganic residue after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against defined standards under controlled lighting conditions. |
| Particle Size Distribution | Laser Diffraction | Measurement of particle size distribution in dry or wet dispersion using Mie scattering theory and laser diffraction optics. |
| Acid Value | Acid-Base Titration | Titration with standardized KOH solution in ethanol/isopropanol mixture using phenolphthalein indicator to determine free carboxylic acid groups. |
| Bromine Content | Oxygen Flask Combustion + Potentiometric Titration | Combustion in oxygen flask to convert organic bromine to bromide, followed by potentiometric titration with silver nitrate. |
