Manufacturing Quality Control of 156699-39-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase C18 column and calibrated standard. |
| Chiral Purity | Chiral HPLC | Separates (S)- and (R)-enantiomers using chiral stationary phase; enantiomeric excess calculated from peak areas. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., THF, EtOAc, MeOH) via flame ionization detection after headspace sampling. |
| Water Content | Karl Fischer Titration | Measures trace water by coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Quantifies elements such as Pb, Cd, Hg, As, and Ni at sub-ppb levels using inductively coupled plasma mass spectrometry. |
| Residual Palladium | ICP-OES | Determines palladium content from catalyst residues using inductively coupled plasma optical emission spectroscopy. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid groups via titration with standardized NaOH solution using phenolphthalein indicator. |
| Optical Rotation | [alpha]D Measurement | Determines specific rotation using sodium D-line light source to confirm chiral integrity and concentration. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample to report D10, D50, D90 values based on light scattering intensity vs. angle. |
| Residual Chloride | Ion Chromatography | Quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally related impurities (e.g., deprotected forms, diastereomers) using gradient reverse-phase method. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms and absence of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial methods. |
