Manufacturing Quality Control of DL-LEUCIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies free carboxylic acid groups by neutralization with standardized sodium hydroxide solution. |
| Optical Rotation | Polarimetry | Measures the angle of rotation of plane-polarized light caused by chiral molecules in solution. |
| Water Content | Karl Fischer Titration | Determines water via stoichiometric reaction between water, iodine, sulfur dioxide, and a base in methanol. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities remaining after high-temperature ashing. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies metal impurities (e.g., Pb, Cd, As) by measuring absorption of specific wavelengths of light. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions via precipitation titration using silver nitrate and a silver indicator electrode. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Related Substances | Reverse-Phase HPLC | Separates and quantifies structurally similar impurities using a C18 column and UV detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| pH (1% aqueous solution) | pH Meter Measurement | Measures hydrogen ion activity in dilute aqueous solution to assess acidity and potential degradation. |
| Appearance | Visual Inspection | Evaluates physical state, color, and clarity against established reference standards under controlled lighting. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measures weight loss upon heating to remove volatile components including residual solvents and moisture. |
