Manufacturing Quality Control of 2,5-DIBROMOPHENOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 275 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-brominated isomers, dibromo-benzenediols) using gradient HPLC-UV against reference standards. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, toluene) based on retention time and calibration curves. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, using plasma excitation and elemental emission intensities. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against NaCl calibration standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or discoloration against white background under controlled lighting. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized KOH ethanol solution, using phenolphthalein indicator or potentiometric endpoint. |
| Ash Content | Gravimetric Analysis | Incineration at 550-600 C to oxidize organic matter, followed by weighing of residual inorganic ash. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to determine D10, D50, D90 values per ISO 13320. |
| Bulk Density | Tap Density Measurement | Measurement of mass per unit volume after standardized tapping (ASTM D1895 Method A) for flowability assessment. |
