Manufacturing Quality Control of DIETHYL 5-BROMOISOPHTHALATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-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 threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual ethyl acetate, ethanol, and toluene against calibrated standards. |
| Moisture Content | Karl Fischer Titration | Volumetric titration using iodine-based reagent to determine water content via stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, and As after acid digestion, using plasma emission spectroscopy with matrix-matched calibration. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in solution after sample dissolution and filtration. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by weighing of non-volatile residue after treatment with sulfuric acid. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated digital apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of color and physical state (white to off-white crystalline powder) against standard reference under controlled lighting. |
| Acid Value | Acid-Base Titration | Titration with standardized potassium hydroxide solution to quantify free carboxylic acid groups from hydrolysis. |
| Ethyl Ester Content | 1H NMR Spectroscopy | Quantitative analysis using integration of ethyl group protons (CH3 and CH2) relative to aromatic protons as internal reference. |
| Particle Size Distribution | Laser Diffraction | Measurement of size distribution in dispersed phase using Mie scattering theory and validated instrument calibration. |
