Industrial Applications of 2-AMINO-5-METHOXYPYRIMIDINE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Key intermediate for synthesizing antimalarial drugs chloroquine and hydroxychloroquine | Condensed with 4,7-dichloroquinoline under alkaline conditions, followed by cyclization and hydrolysis to yield the target drug |
| Agrochemicals | Structural building block for pyrimidine fungicides (e.g., triadimefon) | Used as a starting material in heterocycle construction; active functional groups are introduced via substitution and oxidation reactions |
| Dyes & Pigments | Intermediate for azo dyes and fluorescent whitening agents | After diazotization, coupled with aromatic amines; alternatively serves as an electron donor in conjugated system design |
Manufacturing Quality Control of 2-AMINO-5-METHOXYPYRIMIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 260-280 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 threshold limits per ICH Q3A/B. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine water content via stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight and measuring inorganic residue as percentage of original mass. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against NaCl calibration standards. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample with sulfuric acid followed by high-temperature ashing and gravimetric determination of residual sulfates. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and wavelength (e.g., 589 nm). |
| Organic Volatile Impurities (Residual Solvents) | GC-FID | Headspace GC with flame ionization detection for quantification of solvents (e.g., methanol, acetone, DMF) per ICH Q3C. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to calculate volume-based particle size distribution in dispersed suspension. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in saturated aqueous solution using calibrated glass electrode and pH meter. |
