Manufacturing Quality Control of 4-(3-Butenyl)benzoic acid 4-cyano-3,5-difluorophenyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, ethyl acetate, toluene) by headspace GC with flame ionization detection against 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, As, Hg, Ni) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled charring and sulfuric acid treatment, followed by high-temperature ignition and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light source to assess chiral purity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample to determine D10, D50, D90 values based on light scattering intensity vs. angle. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined saturated suspension using calibrated glass electrode and pH meter. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtering sample through membrane, incubating on soybean-casein digest agar, and enumerating colony-forming units. |
