Industrial Applications of DIETHYL 3 4-PYRIDINEDICARBOXYLATE 97
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used in synthesizing pyrimidine-containing heterocycles, such as precursors to anticancer, antibacterial, or antiviral agents | Acts as a diester component for pyrimidine ring construction, participating in condensation, cyclization, or functional group transformation reactions |
| Organic Synthesis | Serves as a versatile synthetic building block for constructing complex molecules containing a pyrimidine scaffold | Introduces carboxylic acid, amide, or alkyl side chains via hydrolysis, aminolysis, reduction, or cross-coupling reactions |
| Pesticide Development | Applied in developing novel herbicidal or insecticidal active ingredients featuring a pyrimidine structure | Functions as a core structural unit; structural modifications optimize biological activity and selectivity |
| Materials Science | Used in preparing pyrimidine-containing ligand-based metal–organic frameworks (MOFs) or functional polymers | Acts as a rigid linker or coordination precursor, enabling the construction of porous or optoelectronic materials via transesterification or polymerization reactions |
Manufacturing Quality Control of DIETHYL 3 4-PYRIDINEDICARBOXYLATE 97
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 220 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities based on retention time and UV spectral matching; quantified relative to main peak. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., ethanol, ethyl acetate) per ICH Q3C. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to determine trace water content via stoichiometric reaction. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride anions in aqueous extract following sample dissolution and filtration. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by sulfuric acid treatment and final weighing of residual inorganic ash. |
| Appearance | Visual Inspection | Assessment of color and clarity of substance in solution (e.g., 10 mg/mL in ethanol) against water-white standard. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid using calibrated capillary tube method. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution to assess chiral purity. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after controlled heating at 600 C for specified duration. |
