| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Antiviral agent for the treatment of herpes virus infections | Chemical synthesis and crystallization purification |
| Biochemical Research | Nucleoside analog used to study DNA synthesis and cellular proliferation mechanisms | Laboratory-scale synthesis and chromatographic separation |
| Pharmaceutical Intermediates | Intermediate in the synthesis of other antiviral or antineoplastic agents | Catalytic reaction and solvent extraction |
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Determine the absorption peak of the sample at specific wavelengths (e.g., 270–280 nm) and compare with the reference standard spectrum for identification. |
| Infrared Spectrophotometry (IR) | Measure the infrared spectrum of the sample using KBr pellet method, and compare with the standard spectrum to confirm molecular structural characteristics. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column, with phosphate buffer-methanol as mobile phase, and ultraviolet detector (~270 nm) for detection. Calculate the content of the main component by external standard method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate impurities using gradient or isocratic elution program, detect degradation products or synthesis intermediates, and calculate impurity limits by area normalization or reference standard method. |
| Moisture | Karl Fischer Titration | Directly determine the moisture content of the sample using volumetric or coulometric methods, suitable for quality control of moisture-sensitive drugs. |
| Solution Clarity | Visual Turbidity Method | Dissolve the sample in water or specified solvent, and compare with standard turbidity solution to determine if the solution is clear. |
| Solution Color | Visual Colorimetry or Colorimeter Method | Compare the color of the solution with standard color solutions (e.g., yellow or brown series) to assess whether the color is within acceptable limits. |
| pH Value | pH Meter Method | Prepare the sample solution at a certain concentration and measure its pH value using a calibrated pH meter, keeping it within the specified range. |
| Heavy Metals | Sulfide Colorimetric Method (Chinese Pharmacopoeia Method) | Under acidic conditions, heavy metals react with hydrogen sulfide to form colored precipitates, which are quantitatively compared with standard lead solution. |
| Residue on Ignition | Residue on Ignition Test Method | Ignite the sample at high temperature until constant weight, weigh the residue, and calculate the content of non-volatile inorganic impurities. |
| Microbial Limit | Microbial Limit Test Method | Perform tests for total aerobic bacteria count, mold and yeast count, and control organisms (e.g., Escherichia coli) according to pharmacopoeia requirements. |
| Bacterial Endotoxins | Limulus Amebocyte Lysate (LAL) Method | Use Limulus reagent to detect bacterial endotoxins through gel formation or color development, and quantify the endotoxin content in the sample. |
