Manufacturing Quality Control of H-D-ARG(TOS)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 210-220 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities using gradient HPLC with UV detection and relative response factor correction. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, DMF) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-MS | Quantification of trace metal impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion, using inductively coupled plasma mass spectrometry for multi-element detection. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions after aqueous extraction and filtration; quantified via calibration curve. |
| Sulfate Impurity | Ion Chromatography | Anion exchange chromatography with suppressed conductivity detection to measure sulfate content following sample dissolution and dilution. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration (500-600 C) followed by weighing of residual residue. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light (589 nm) in solution to confirm chiral integrity and enantiomeric purity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of pH in a defined aqueous suspension or solution using a calibrated glass electrode and pH meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample by measuring angular scattering intensity of laser light to derive volume-based particle size distribution. |
| Microbial Contamination | Membrane Filtration | Enumeration of aerobic microorganisms by filtration, membrane transfer to culture media, incubation, and colony counting per pharmacopeial guidelines. |
