| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of steroid drugs | Used as a precursor in the synthesis of testosterone derivatives |
| Animal Nutrition | Growth promoters | Incorporated into animal feed to support growth |
| Livestock Farming | Growth promotion | Applied in livestock rearing to enhance productivity |
| Test Item | Common Testing Method | Method Description |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | The sample and reference standard are analyzed under identical conditions for infrared absorption spectra. Characteristic peak positions and intensities are compared to confirm structural consistency. |
| High-Performance Liquid Chromatography (HPLC) | Retention time is compared to confirm the identity of the main component with the reference standard, often used in conjunction with other tests. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | A reversed-phase column (e.g., C18) and a UV detector (approximately 254 nm) are used. Quantification of the main component is performed using external standard or internal standard methods. |
| UV-Visible Spectrophotometry (UV-Vis) | Trenbolone enanthate's characteristic absorption at specific wavelengths (e.g., 240–254 nm) is utilized for content determination via standard curve method (less commonly used for precise quantification). | |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Gradient elution is used to separate degradation products and synthetic intermediates. Impurity content is calculated using peak area normalization or external standard method with reference standards. |
| Residual Solvents | Gas Chromatography (GC) | According to pharmacopoeial methods (e.g., ChP, USP), organic solvents (e.g., methanol, acetone, ethyl acetate) remaining from the manufacturing process are detected. |
| Moisture | Karl Fischer Titration | Accurately measures moisture content in the sample, suitable for quality control of raw materials. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Detects heavy metal elements such as lead, cadmium, and mercury, ensuring compliance with safety limits for medicinal raw materials. |
| Particle Size Distribution | Laser Diffraction Analysis | For microcrystalline injectable formulations, particle size distribution must be controlled to ensure bioavailability and safety. |
| Crystallinity Analysis | X-ray Diffraction (XRD) | Identifies different crystal forms to ensure product crystalline stability, which affects solubility and stability. |
| Melting Point | Capillary Melting Point Determination | Measures the melting temperature range of the compound as one of the physical property identification indicators. |
