Manufacturing Quality Control of Guanosine-5'-diphosphate disodium salt
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance and Physical Characteristics | Visual Inspection + Physical Property Determination | Observe sample as white or off-white crystalline powder, free from visible foreign matter; determine solubility (freely soluble in water, insoluble in ethanol) |
| Identification Test | UV-Visible Spectrophotometry (UV-Vis) | Exhibits characteristic absorption peak near 248 nm; confirm structural features by comparing absorption spectra with reference standard. Thin-layer chromatography (TLC) may also be used to identify by comparing Rf values with reference substance. |
| Identification Test | High-Performance Liquid Chromatography (HPLC) | Use C18 column with buffer-methanol mobile phase; confirm active ingredient by comparing retention time with reference standard |
| Assay (Content Determination) | High-Performance Liquid Chromatography (HPLC) | Quantify GDP-Na₂ content using external or internal standard method with UV detection at 248 nm; meet pharmacopoeial requirements (e.g., ≥98.0%) |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use gradient elution to detect potential impurities such as GMP, GTP, guanine, etc.; calculate percentage of impurity peak areas, which must not exceed specified limits (e.g., ≤1.0%) |
| Moisture Content | Karl Fischer Titration | Accurately determine moisture content and control within specified range (e.g., ≤5.0%) to ensure stability and solubility |
| Solution Clarity and Color | Visible Colorimetry / Spectrophotometry | Prepare solution at specified concentration; assess clarity and color visually or by measuring absorbance at 500–600 nm using spectrophotometer to confirm clear and colorless appearance |
| pH Value | pH Meter Measurement | Prepare 1% aqueous solution and measure pH using calibrated pH meter; maintain pH within specified range (typically 6.0–8.0) for chemical stability |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Process sample according to pharmacopoeial method; determine levels of heavy metals such as lead, arsenic, cadmium, mercury; ensure concentrations are below permissible limits (e.g., ≤10 ppm) |
| Sulfate | Turbidimetric Method (Chinese Pharmacopoeia Method) | Add barium chloride to form barium sulfate precipitate; compare turbidity with standard sulfate solution to control sulfate content within acceptable limits |
| Chloride | Silver Nitrate Titration / Turbidimetric Method | Add silver nitrate reagent to form silver chloride precipitate; compare turbidity with standard chloride solution to control chloride content within limit (e.g., ≤0.1%) |
| Microbial Limits | Plate Count Method / MPN Method | Test for total aerobic microbial count, molds and yeasts, and presence of Escherichia coli; comply with microbial limits for non-sterile pharmaceuticals |
| Pyrogen or Bacterial Endotoxins | Limulus Amebocyte Lysate Test (LAL Test) | If used as raw material for injectables, test bacterial endotoxin level; typical limit ≤0.25 EU/mg (depending on route of administration) |
| Purity (¹H-NMR) | Nuclear Magnetic Resonance Spectroscopy (NMR) | Used for high-precision structural confirmation; verify chemical purity and structural integrity through integration ratios of characteristic proton signals (e.g., H-8, H-2, sugar ring protons) |
