Industrial Applications of 2,3-Dibromofuran-5-carboxylic acid
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate for synthesizing antifungal agents (e.g., terbinafine analogues) | Bromination–oxidation of 2-furaldehyde: 2-Furaldehyde is subjected to bromination followed by oxidation |
| Organic Synthesis | Building block for brominated heterocyclic compounds; participates in cross-coupling reactions such as Suzuki coupling | Palladium-catalyzed cross-coupling: reacts with arylboronic acids under Pd(PPh₃)₄/K₂CO₃ to introduce aryl substituents |
| Materials Science | Monomer precursor for functionalized biodegradable polymers, used to modulate polarity and crystallinity of polyester segments | Polycondensation: high-temperature melt polycondensation with diols (e.g., ethylene glycol) catalyzed by p-toluenesulfonic acid |
Manufacturing Quality Control of 2,3-Dibromofuran-5-carboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 220-254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities (e.g., mono-bromo, tri-bromo, or decarboxylated analogs) via gradient HPLC-UV against qualified reference standards. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, ethyl acetate, toluene) based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content by stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, using plasma emission spectroscopy calibrated with matrix-matched standards. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against NaCl calibration standards. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700-800 C) to determine inorganic ash content. |
| 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 established reference samples under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Measurement of particle size distribution in dry or dispersed state using light scattering principles and Mie theory. |
| Acid Value | Acid-Base Titration | Titration with standardized NaOH solution using phenolphthalein indicator to determine free carboxylic acid content. |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after mechanical tapping per USP <616> to assess flow and handling properties. |
