| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Assay | Gas Chromatography (GC) | Capillary column gas chromatography with a hydrogen flame ionization detector (FID). Quantification of fenvaleric acid using external or internal standard methods, offering high resolution and sensitivity. |
| High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with UV detection (approximately 210–230 nm). Suitable for thermally unstable samples and effective in separating isomers. | |
| Purity and Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation capability of GC with the qualitative power of MS to identify organic impurities, isomers, and degradation products in fenvaleric acid. |
| HPLC-DAD or LC-MS | Used for qualitative and quantitative analysis of fenvaleric acid and related impurities in complex matrices, especially suitable for detecting non-volatile or thermally unstable impurities. | |
| Moisture Content | Karl Fischer Titration | Determines trace water content precisely based on the reaction of iodine and sulfur dioxide with water in an anhydrous environment. This is the standard method for moisture determination. |
| Acid Value | Acid-Base Titration | Dissolve sample in ethanol and titrate with standardized sodium hydroxide solution to calculate the acid value, reflecting free acid content and stability of fenvaleric acid. |
| Residual Solvents | Gas Chromatography (Headspace Sampling) | Headspace sampling coupled with GC-FID to detect residual organic solvents (e.g., methanol, ethanol, acetone) from manufacturing processes, compliant with pharmacopoeial requirements. |
| Crystal Form Analysis | X-Ray Diffraction (XRD) | Analyzes the crystal structure of fenvaleric acid to determine polymorphism, which affects solubility and stability. |
| Thermal Stability | Differential Scanning Calorimetry (DSC) | Measures melting point, phase transition temperatures, and thermal decomposition behavior to evaluate thermal stability and purity of fenvaleric acid. |
| Particle Size Distribution | Laser Particle Size Analysis | Applied to solid powder samples to determine particle size distribution of fenvaleric acid, influencing formulation uniformity and bioavailability. |
