| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Pharmaceutical intermediates (e.g., for synthesis of antitumor and antiviral agents) | Used in organic synthesis and catalytic reactions |
| Agrochemicals | Active ingredients or intermediates for insecticides and herbicides | Applied in condensation and esterification reactions |
| Research | Chemical reagent for structural modification studies of pyrimidine compounds | Employed in laboratory-scale synthesis |
| Materials Science | Monomer for synthesizing polymeric or functional materials | Utilized in polymerization and material modification processes |
| 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-DAD | Detects and quantifies impurities by HPLC with diode-array detection, identifying peaks via retention time and spectral match. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., ethanol, ethyl acetate) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange separation. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration of sample with sulfuric acid, followed by weighing of residual ash. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against standard reference under controlled lighting. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid content by titration with standardized NaOH solution using phenolphthalein indicator. |
| Loss on Drying | Thermogravimetric Analysis | Quantifies volatile matter by measuring weight loss after heating sample at 105 C for 2 hours under controlled atmosphere. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity and identity by measuring rotation angle of plane-polarized light passing through solution. |
