Manufacturing Quality Control of (-)-Corey lactone diol
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Compares the infrared absorption spectra of the sample with those of reference standards to confirm the presence and matching of characteristic functional groups (e.g., hydroxyl, lactone ring). |
| High-Performance Liquid Chromatography (HPLC) | Under specific chromatographic conditions, compares retention times of the main peak between test sample and reference standard for qualitative identification. | |
| Content Determination | High-Performance Liquid Chromatography with Ultraviolet Detection (HPLC-UV) | Uses a reversed-phase C18 column and UV detector (e.g., 210–254 nm), with quantification performed via external or internal standard method for determination of the main component. |
| Potentiometric Titration | If the molecule contains acidic/basic functional groups, non-aqueous titration or potentiometric titration may be used for content determination (less commonly applied for complex lactone structures). | |
| Impurities / Related Substances Testing | HPLC with Gradient Elution | Utilizes gradient elution to separate the main component from potential process impurities and degradation products; impurity levels are calculated using area normalization or self-reference method. |
| Residual Solvents | Gas Chromatography (GC-FID or GC-MS) | Headspace or direct injection is employed to detect residual organic solvents (e.g., methanol, ethyl acetate) according to ICH Q3C guidelines. |
| Drying Loss | Drying Method | Dried at a specified temperature (e.g., 105°C) until constant weight; measures the percentage loss due to moisture and volatile substances. |
| Residue on Ignition | Gravimetric Method | Sample is ignited at high temperature (700–800°C), then weighed to determine total inorganic residue, assessing overall inorganic impurity levels. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Per Chinese Pharmacopoeia general rules, detects residual heavy metals such as lead, cadmium, arsenic, mercury, and copper to ensure compliance with safety limits. |
| Water Content | Karl Fischer Titration | Used for trace water determination, especially suitable for hygroscopic compounds or those containing crystalline water. |
| Specific Rotation | Measurement by Polarimeter | If the molecule has chiral centers, specific rotation is measured to control stereochemical purity. |
| pH Value | pH Meter Measurement | For solution formulations or raw materials requiring pH control, the pH of the aqueous solution is determined. |
| Particle Size Distribution (if applicable) | Laser Particle Size Analyzer | Controls physical properties of active pharmaceutical ingredients, influencing dissolution behavior and formulation performance. |
