| Chemical manufacturing | Organic synthesis | Served as a raw material for synthesizing organic sulfur compounds |
Manufacturing Quality Control of Benfotiamine
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Perform infrared scanning of the sample and reference standard within the range of 4000–400 cm⁻¹, and compare characteristic absorption peaks to confirm molecular structural consistency. |
| High-Performance Liquid Chromatography (HPLC) | Confirm identity by comparing retention times—verify that the chromatographic peak of benphosphthiamine in the sample matches that of the reference standard for qualitative identification. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (typically at 246 nm or 275 nm), and quantify the main component using external or internal standard methods. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Employ gradient elution to separate impurities, detect degradation products or synthesis intermediates, calculate individual impurity peak areas, and assess purity. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace sampling to detect residual organic solvents (e.g., methanol, ethanol, acetone) from manufacturing processes, ensuring compliance with pharmacopoeial limits. |
| Water Content | Karl Fischer Titration | Accurately determine water content in the sample via electrochemical titration; suitable for quality control of solid samples with low moisture levels. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and measure elemental concentrations of heavy metals such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmaceutical safety standards. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Measure the particle size distribution of the active pharmaceutical ingredient, which affects solubility and bioavailability; commonly used for pre-formulation quality assessment. |
| Polymorphic Form Analysis | X-Ray Powder Diffraction (XRD) | Analyze the crystal structure of benphosphthiamine to ensure batch-to-batch consistency in crystalline form, avoiding differences in stability or dissolution due to polymorphic variation. |
| Melting Point | Melting Point Determination | Determine the melting temperature range using a melting point apparatus; serves as a physical property identifier and an indicator of purity. |
