Manufacturing Quality Control of D-Tyrosine
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | High-Performance Liquid Chromatography (HPLC) | Distinguishes D-tyrosine from L-tyrosine based on differences in retention time on a chiral column to confirm chemical structure. |
| Infrared Spectroscopy (IR) | Compares the sample's infrared absorption spectrum with a standard reference spectrum to confirm functional groups and molecular structural features. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Quantifies D-tyrosine content using reversed-phase or chiral HPLC, offering high sensitivity, high resolution, and excellent reproducibility. |
| Amino Acid Automatic Analyzer | Based on ion-exchange chromatography and post-column derivatization; specifically designed for precise quantification of amino acids in complex matrices. | |
| Optical Purity | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Uses a chiral stationary phase column to separate D- and L-tyrosine enantiomers, evaluating enantiomeric excess (ee value) to control optical purity. |
| Optical Rotation Measurement | Measures the specific optical rotation of the sample solution and compares it with the theoretical value to preliminarily assess enantiomeric composition and purity. | |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Checks for possible organic impurities (e.g., L-tyrosine, other amino acids, or degradation products) to evaluate purity and impurity limits. |
| Water Content | Karl Fischer Titration | Accurately determines moisture content in the sample; suitable for trace water detection to ensure stability and storage quality. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Oven Method | Heats the sample at a specified temperature and measures the percentage weight loss to assess volatile components (including moisture and residual solvents). |
| Residue on Ignition | Sulfated Ash Test | The sample is treated with sulfuric acid and then incinerated at high temperature to determine the amount of non-volatile inorganic impurities remaining. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Detects heavy metal elements such as lead, mercury, cadmium, and arsenic to ensure compliance with pharmacopeial or food safety limits. |
| Microbial Limits | Microbial Limit Test | Performs tests according to pharmacopeial requirements, including total aerobic microbial count, mold and yeast count, and control organism testing (e.g., E. coli, Salmonella). |
