Manufacturing Quality Control of 3-isobutylglutaric anhydride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Measures milligrams of KOH required to neutralize acidic groups in 1 g sample. |
| Moisture Content | Karl Fischer Coulometric Titration | Electrochemically determines water content based on iodine generation stoichiometry. |
| Residue on Ignition | Gravimetric Analysis after high-temperature ashing | Measures non-volatile inorganic residue mass remaining after combustion at 700-800 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metal concentration by atomic absorption of characteristic wavelength light. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using conductivity detection after anion exchange. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Identifies and quantifies structurally related impurities via retention time and UV absorbance. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid under controlled heating. |
| Specific Optical Rotation | Polarimetry | Determines degree of rotation of plane-polarized light caused by chiral molecules in solution. |
| Appearance | Visual Inspection against standard reference | Assesses physical state, color, and clarity by comparison to specified visual criteria. |
| Solubility in Common Solvents | Qualitative Solubility Test | Evaluates complete dissolution in specified solvents (e.g., acetone, ethyl acetate) at defined conditions. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects and quantifies low-boiling residual solvents by analysis of vapor phase above sample. |
