Manufacturing Quality Control of 7-HYDROXYHEPTANOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies carboxylic acid content by titration with standardized NaOH using phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Measures water via iodine-sulfur dioxide redox reaction in a methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Detects metal contaminants (e.g., Pb, Cd, Fe) by measuring absorbance of element-specific atomic vapor. |
| Chloride Content | Potentiometric Titration | Quantifies chloride ions using silver nitrate titrant and silver/silver chloride electrode. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic sulfate residues after combustion with sulfuric acid treatment and ignition. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally similar impurities using reversed-phase C18 column and UV detection. |
| Color | Visual Comparison or Spectrophotometry | Evaluates appearance against standard platinum-cobalt color scale or measures absorbance at specified wavelength. |
| Melting Point | Capillary Melting Point Determination | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity by detecting rotation of plane-polarized light in solution. |
| pH of Aqueous Solution | pH Meter Measurement | Determines acidity/basicity of 1% w/v aqueous solution using calibrated glass electrode. |
| Volatile Impurities | Gas Chromatography (GC) | Identifies and quantifies low-boiling organic impurities using flame ionization detection. |
