Industrial Applications of ETHYL 4-AMINO-2-MERCAPTOPYRIMIDINE-5-CARBOXYLATE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of antiviral agents (e.g., adefovir dipivoxil precursors) and pyrimidine nucleoside analogues | Used as a key intermediate in multi-step reactions—including acylation, cyclization, and hydrolysis—to construct the active molecular core |
| Agrochemicals | Synthesis of novel pyrimidine-based fungicides and plant growth regulators | Applied in condensation reactions with haloalkanes or aldehydes to introduce substituents that enhance biological activity |
| Dyes & Pigments | Production of azo dyes and metal-complex dyes containing thiol and amino groups | Used for diazotization via the amino group; the thiol group participates in coordination or coupling reactions to improve color fastness |
Manufacturing Quality Control of ETHYL 4-AMINO-2-MERCAPTOPYRIMIDINE-5-CARBOXYLATE
| 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 matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., ethanol, ethyl acetate) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generation in pyridine-free reagent; water reacts stoichiometrically with iodine and sulfur dioxide. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion; detection based on characteristic atomic emission spectra of metals in plasma. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with conductivity detection; chloride quantified via calibration curve. |
| Sulfur Content (as thiol) | Iodometric Titration | Oxidation of free -SH group by standardized iodine solution; endpoint detected by starch indicator color change. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually as solid-to-liquid phase change in capillary tube under controlled heating rate. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying sample at 105 C for 2 hours under vacuum or nitrogen purge. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against established reference standards. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
| Residue on Ignition | Gravimetric Ashing | Weight of non-volatile inorganic residue determined after high-temperature (600-700 C) ashing of sample in platinum crucible. |
