Manufacturing Quality Control of 3,5-DIBROMO-4-PYRIDINOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., mono-bromo, debromo, or oxidation by-products) via gradient HPLC separation and UV response. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone, DMF) using gas chromatography with flame ionization detection against certified standards. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine consumption in pyridine-methanol buffer. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other regulated metals after acid digestion, using plasma excitation and elemental emission intensity. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against established reference standard under controlled lighting. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in dry or wet dispersion by analyzing angular scattering pattern of laser beam. |
