Manufacturing Quality Control of 33769-07-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, relative to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV against reference standards or threshold-based area normalization. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, THF, toluene) by headspace GC with flame ionization detection using calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni, As) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Sulfate Content | Ion Chromatography | Separates and quantifies sulfate ions using suppressed conductivity detection following sample dissolution and dilution. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled ashing at 700-800 C and weighing of the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity and identity by determining rotation of plane-polarized light in solution at specified concentration and wavelength. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed powder to determine volume-based particle size distribution using Mie scattering theory. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic mesophilic microorganisms and detects specified pathogens (e.g., E. coli) per USP <61> and <62>. |
