| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Intermediate | Used in the synthesis of active pharmaceutical ingredients (APIs) |
| Chemical Industry | Synthetic Raw Material | Used to prepare other chemicals or drug molecules |
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe sample color, physical state (e.g., white to off-white crystalline powder), presence of foreign matter, or caking due to moisture absorption. |
| Identification | Infrared Spectrophotometry (IR) | Compare characteristic absorption peaks of the sample with those of a reference standard to confirm consistency in molecular functional groups. |
| High-Performance Liquid Chromatography (HPLC) | Confirm identity by comparing retention time with that of a reference standard. | |
| Assay | HPLC with UV Detection (HPLC-UV) | Use a reversed-phase column and UV detector (e.g., at 254 nm), calculate the content of the main component by external standard method or area normalization method. |
| Related Substances (Impurities) | HPLC Gradient Elution Method | Separate the main peak from potential impurity peaks using a gradient program, and calculate impurity limits by self-reference method or external standard method. |
| Loss on Drying | Drying to Constant Weight (105°C) | Weigh the sample before and after drying at the specified temperature until constant weight is achieved; calculate the percentage loss due to moisture and volatile substances. |
| Residue on Ignition | High-Temperature Ashing (700–800°C) | Ignite the sample at high temperature and weigh the residual inorganic material to assess levels of inorganic salts or metal impurities. |
| Residual Solvents | Gas Chromatography (GC-FID/HS-GC) | Analyze residual organic solvents (e.g., methanol, ethyl acetate) from synthesis or purification using headspace or direct injection methods. |
| Heavy Metals | ChP Heavy Metals Test Method | Determine total levels of harmful metallic elements (e.g., lead, arsenic, cadmium, mercury) using thioacetamide method or ICP-MS. |
| pH Value (if applicable for solution) | pH Meter Measurement | Prepare a solution of defined concentration and measure its pH to ensure compliance with formulation stability requirements. |
| Melting Point | Capillary Melting Point Method | Determine the melting temperature range as a physical constant to assist in identification and purity assessment. |
