Manufacturing Quality Control of 4-Bromo-3,5-dimethylphenol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 275 nm; peak area comparison against certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., bromination by-products, isomers, residual phenols) via gradient HPLC-UV with suitable column and mobile phase. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., methanol, toluene, dichloromethane) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine consumption in pyridine/methanol solvent system. |
| Heavy Metals | ICP-OES | Measures total heavy metal content (Pb, Cd, Hg, As, Cr) after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on anion-exchange column with carbonate eluent. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against specified criteria (white to off-white crystalline powder). |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700–800 C) and weighing. |
| Acid Value | Acid-Base Titration | Determines free acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after ignition with sulfuric acid pretreatment, per USP <281>. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume of freely settled and tapped powder using standardized cylinder and tapping device. |
