Manufacturing Quality Control of Z-ASP(OTBU)-OME
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification by retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, toluene) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based redox reaction in anhydrous pyridine-methanol medium. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma mass spectrometry for sub-ppt sensitivity. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid content by titration with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature (700-800 C) ashing and weighing of the cooled crucible. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample using Mie theory to calculate size distribution based on angular scattering intensity of laser light. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube method under controlled heating rate. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms by filtering sample through sterile membrane, followed by incubation on soybean-casein digest agar and colony enumeration. |
