| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Formulation of combination preparations (e.g., inosine tablets, inosine injection) for adjunctive treatment of leukopenia, thrombocytopenia, and acute/chronic liver diseases | Wet granulation and tablet compression (tablets); dissolution, filtration, filling, and sterilization (injection) |
| Food Industry | Used as a food nutrient fortifier or flavor enhancer to improve food taste | Blended with sodium chloride, monosodium glutamate, and other ingredients |
| Agriculture / Animal Husbandry | Employed as a feed additive to promote livestock and poultry growth and enhance immunity | Directly mixed into basal feed |
| Chemical / Biotechnology Industry | Served as a biochemical reagent in nucleotide biosynthesis or related enzymology studies | Dissolved in buffer solution and incorporated into enzymatic reaction systems |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 260 nm, based on peak area comparison against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., inosine, IMP acid, hydrolysis products) using gradient HPLC-UV; identification by retention time matching and/or spiking. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to quantify water content based on stoichiometric reaction with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Heating sample at 700–800 °C to constant weight; residual inorganic ash mass expressed as percentage of original sample. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of heavy metals (Pb, Cd, As, Hg, Cr) after acid digestion, using plasma excitation and element-specific emission wavelength detection. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a 1% w/v aqueous solution at 25 °C using calibrated glass electrode and pH meter. |
| Specific Optical Rotation | [α]D | Measurement of plane-polarized light rotation in a 1% w/v solution at 20 °C using sodium D-line (589 nm); verifies chiral integrity and identity. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Weight loss measured after drying at 105 °C for 2 hours; reflects volatile content including residual solvents and moisture. |
| Microbial Limits | Membrane Filtration / Plate Count | Enumeration of aerobic mesophilic bacteria and yeasts/molds via membrane filtration followed by incubation on appropriate agar media (e.g., TSA, SDA). |
| Residual Solvents (e.g., Ethanol, Acetone) | GC-FID | Headspace or direct injection GC with flame ionization detection; quantification against certified solvent standards using internal standard calibration. |
| Sodium Content | Flame Photometry or ICP-OES | Quantification of Na⁺ after acid dissolution, based on characteristic emission intensity in flame or plasma excitation. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of chloride anions on anion-exchange column and detection via suppressed conductivity; quantified against chloride standard. |
| Endotoxins (for pharmaceutical-grade) | Kinetic Turbidimetric LAL Assay | Quantitative measurement of endotoxin-induced clotting enzyme activation in Limulus amebocyte lysate, detected as turbidity increase over time. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie scattering theory to determine volumetric particle size distribution (D10, D50, D90). |
