Manufacturing Quality Control of DL-Isoleucine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Isoleucine Content) | Acid-Base Titration with NaOH | Quantitative determination based on neutralization of carboxylic acid group using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Optical Rotation | Polarimetry | Measures the angle of rotation of plane-polarized light caused by chiral DL-isoleucine in solution, indicating enantiomeric composition and purity. |
| Specific Optical Rotation | Polarimetry | Calculates optical rotation normalized to concentration and path length to verify compliance with pharmacopeial specifications. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Determines volatile matter content by measuring mass loss after drying at specified temperature and time under controlled conditions. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Measures non-volatile inorganic impurities by incinerating sample at high temperature and weighing residual ash. |
| Heavy Metals (as Pb) | AAS (Atomic Absorption Spectroscopy) | Quantifies total heavy metals by atomizing the sample and measuring absorbance of characteristic wavelengths for lead. |
| Chloride (Cl-) | Argentometric Titration (Mohr method) | Determines chloride ion concentration via precipitation titration with silver nitrate using potassium chromate indicator. |
| Sulfate (SO42-) | Gravimetric (Barium Sulfate Precipitation) | Measures sulfate as insoluble barium sulfate precipitate formed after addition of barium chloride solution. |
| pH (1% aqueous solution) | Potentiometric (pH meter) | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode system. |
| Related Substances | HPLC (Reverse-Phase) | Separates and quantifies structurally similar impurities using C18 column, UV detection, and gradient elution. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric reaction with iodine generated in situ from KF reagent. |
| Microbial Limits | Membrane Filtration / Plate Count | Assesses aerobic microbial contamination by filtration, culture on appropriate media, and colony enumeration. |
