Manufacturing Quality Control of 4-acetylbutyric acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 5-oxohexanoic acid by retention time and peak area against a certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-based redox reaction. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid groups by titration with standardized sodium hydroxide solution. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption of characteristic wavelength light. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Identifies and quantifies structurally related impurities using reversed-phase separation and UV absorbance. |
| Color | Visual Comparison to APHA Scale | Evaluates color intensity by matching sample solution to standardized platinum-cobalt color solutions. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral centers in the compound. |
| Refractive Index | Refractometry | Determines refractive index using critical angle measurement of light passing through liquid sample. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid phase under controlled heating. |
| Density | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle with temperature control. |
