Manufacturing Quality Control of 140-77-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 3-cyclopentylpropionic acid peak area relative to a calibration curve using an internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and a base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid content by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after controlled high-temperature ashing of sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing sample in flame/graphite furnace and measuring absorbance at characteristic wavelength. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions based on ion exchange retention and conductivity detection. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies structurally related impurities by retention time and mass spectral fragmentation patterns. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Specific Optical Rotation | Polarimetry | Determines rotation of plane-polarized light caused by chiral centers in solution at specified concentration and path length. |
| Refractive Index | Refractometry | Measures bending of light passing through liquid sample at controlled temperature using calibrated refractometer. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling residual solvents by analyzing vapor phase above heated sample vial. |
