Manufacturing Quality Control of 8-HYDROXYOCTANOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies carboxylic acid group by neutralization with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Determines water via coulometric or volumetric reaction between water and iodine generated in situ from KF reagent. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities remaining after high-temperature incineration at 700-800 C. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) by measuring absorption of element-specific UV-Vis radiation. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Related Substances | Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) | Separates and quantifies structurally related impurities using C18 column and UV detection at 210 nm. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus under controlled heating. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against standard reference under controlled lighting conditions. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring angle of rotation of plane-polarized light passing through a solution of the compound. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous suspension using calibrated pH electrode and meter. |
| Iron Content | UV-Vis Spectrophotometry (with 1,10-phenanthroline) | Quantifies Fe2+ after reduction and complex formation; measures absorbance at ~510 nm. |
| Volatile Organic Impurities | Gas Chromatography (GC-FID) | Detects and quantifies residual solvents and low-boiling organics using flame ionization detection and capillary column separation. |
