Industrial Applications of 2,5-DIBROMO-3-METHYLTHIOPHENE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key structural motif for synthesizing anticancer agents, antimicrobial agents, and kinase inhibitors | Used as a brominated heterocyclic building block in cross-coupling reactions—including Suzuki and Heck couplings—to construct biologically active molecules containing thiophene scaffolds |
| Organic Electronic Materials | Preparation of conjugated polymers as donor materials for organic photovoltaics (OPV) and organic field-effect transistors (OFET) | Polymerized via Stille or Kumada coupling with distannyl or dimagnesium reagents to form brominated thiophene copolymer units bearing alkyl side chains, enabling energy-level and crystallinity tuning |
| Agrochemical R&D | Heterocyclic core-modification intermediate for novel insecticides and fungicides | Functionalized with groups such as trifluoromethyl or cyano via lithium–halogen exchange, followed by condensation with active fragments to optimize target-binding activity |
Manufacturing Quality Control of 2,5-DIBROMO-3-METHYLTHIOPHENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-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 relative to reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., acetone, methanol, toluene) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using plasma excitation and optical emission detection. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled ashing at 700-800 C, expressed as weight percent. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus per USP/EP guidelines. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference samples under standardized lighting and viewing conditions. |
| Bulk Density | Graduated Cylinder Method | Measurement of mass per unit volume for free-flowing powder using a calibrated cylinder and tapping procedure per ASTM D1895. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution by measuring angular variation in laser light scattering from a dispersed sample. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light induced by chiral molecules in solution, using sodium D-line at specified concentration and path length. |
