Industrial Applications of 2,4-Dichlorothieno[2,3-d]pyrimidine
| Industry | Application | Process |
|---|---|---|
| Pesticides | Intermediate for herbicides, used in the synthesis of thienopyrimidine herbicides (e.g., pyribenzoxim, bispyribac-sodium) | Undergoes nucleophilic substitution with aromatic amines or phenols under basic conditions to construct the pyrimidine ring side chain; alternatively participates in heterocycle formation via oxidation, coupling, and related steps |
| Pharmaceuticals | Structural motif for antibacterial and antiviral drug candidates | Used to construct biologically active thienopyrimidine heterocyclic scaffolds, commonly applied in medicinal chemistry for structural modification and structure–activity relationship studies |
| Organic Synthesis | Intermediate for heterocyclic functional materials and fluorescent probe molecules | Introduces conjugated groups—such as via lithiation–borylation, Suzuki coupling, or Pd-catalyzed cross-coupling—to extend the π-conjugated system |
Manufacturing Quality Control of 2,4-Dichlorothieno[2,3-d]pyrimidine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at characteristic wavelength, calibrated against certified reference standard. |
| Related Substances | HPLC-DAD or HPLC-MS | Separation and identification of impurities based on retention time and spectral/mass data relative to main peak. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine-based reagent to determine trace water content in sample. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion and isotopic detection. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode to measure total chloride ion concentration. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled lighting and white background. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue after high-temperature ashing at 600-800 C in platinum crucible. |
| Particle Size Distribution | Laser Diffraction | Measurement of size distribution in dispersed powder sample using Mie scattering theory and optical detection. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Specific Optical Rotation | Polarimetry | Determination of chiral rotation angle using sodium D-line light through a solution in specified solvent and path length. |
