Manufacturing Quality Control of EXO-7-OXABICYCLO[2.2.1]HEPTANE-2,3-DICARBOXYLIC ANHYDRIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 210-230 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities using gradient HPLC-UV; identification by retention time matching and/or spiked reference standards. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, ethyl acetate) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-pptr sensitivity. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration (500-600 C) followed by precise weighing of residual residue. |
| Specific Optical Rotation | Polarimetry | Determination of chiral purity and identity by measuring the angle of rotation of plane-polarized light in a solution at specified concentration and wavelength. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using controlled heating of a capillary sample; endpoint defined as the temperature range over which solid-to-liquid phase change occurs. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie scattering theory to derive volume-based particle size distribution. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode and pH meter. |
| Microbial Limits | Membrane Filtration and Colony Counting | Enumeration of aerobic mesophilic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) following USP <61> and <62>. |
| Organic Volatile Impurities (OVI) | GC-MS | Targeted and non-targeted screening of low-level volatile organic impurities using gas chromatography coupled with mass spectrometric detection and library matching. |
