Manufacturing Quality Control of Z-MEALA-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV absorbance at 200-220 nm. |
| Optical Rotation | [alpha]D measurement | Determination of specific rotation using a polarimeter to confirm chiral integrity and enantiomeric excess. |
| Water Content | Karl Fischer titration | Volumetric or coulometric titration where iodine reacts stoichiometrically with water in a controlled anhydrous medium. |
| Residual Solvents | Gas Chromatography (GC-FID) | Separation and quantification of volatile organic solvents using capillary GC with flame ionization detection. |
| Heavy Metals | ICP-MS | Multi-element detection and quantification of trace metals (e.g., Pb, Cd, Hg, As) after acid digestion and plasma ionization. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity-based quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography (IC) | Separation and conductivity-based quantification of sulfate ions using anion-exchange column and suppressed conductivity detection. |
| Related Substances | HPLC with UV detection | Identification and quantification of structurally related impurities (e.g., diastereomers, degradants) using gradient reversed-phase HPLC. |
| pH (1% aqueous solution) | Potentiometric pH measurement | Determination of hydrogen ion activity in aqueous solution using calibrated glass electrode and pH meter. |
| Loss on Drying (LOD) | Thermogravimetric analysis (TGA) or oven drying | Measurement of mass loss upon heating under controlled temperature and time to determine volatile content including residual solvents and moisture. |
| Residue on Ignition (Sulfated Ash) | Gravimetric analysis after sulfuric acid treatment | Conversion of non-volatile residues to sulfates by acid treatment and high-temperature ignition, followed by ash weight measurement. |
| Microbial Limits | Membrane filtration and plate count | Enumeration of aerobic microorganisms using membrane filtration, culture on soybean-casein digest agar, and colony counting after incubation. |
