Manufacturing Quality Control of 9-HYDROXYNONANOIC 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 or potentiometric endpoint detection. |
| Appearance | Visual Inspection | Assessment of 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 per USP/Ph. Eur. guidelines. |
| Water Content | Karl Fischer Titration | Determines trace water via iodine-sulfur dioxide reaction in methanol-based reagent with coulometric or volumetric detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by ignition at 700-800 C and weighing residual ash. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies lead, cadmium, mercury, and arsenic after acid digestion using element-specific hollow cathode lamps. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using anion-exchange column with conductivity detection. |
| Related Substances | Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) | Separates and quantifies structurally related impurities using C18 column, UV detection at 210 nm, and external standard calibration. |
| Organic Volatile Impurities | Gas Chromatography (GC) with FID | Detects residual solvents (e.g., ethanol, acetone, ethyl acetate) using capillary column and flame ionization detection. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity by determining rotation angle of plane-polarized light at specified wavelength and concentration. |
| Acid Value | Acid-Base Titration with KOH | Determines total acidity (mg KOH/g sample) via titration with standardized potassium hydroxide in ethanol. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Quantifies volatile content by measuring mass loss upon heating to 105 C under nitrogen atmosphere for 2 hours. |
