Manufacturing Quality Control of 7-Amino-3-cephem-4-carboxylic acid
| Test Item | Commonly Used Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectrophotometry (IR) | Determine the infrared absorption spectrum of the sample and compare it with the standard spectrum to confirm consistency of characteristic functional group peaks. |
| High-Performance Liquid Chromatography (HPLC) | Identification is performed by comparing the retention time of the sample with that of a reference standard under the same chromatographic conditions. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Utilizes a reversed-phase C18 column and a UV detector (typically at 254 nm or 260 nm), with external or internal standard method to determine the content of the main component. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Employs gradient or isocratic elution to separate and quantify process-related impurities and degradation products, such as Δ²-isomer, 7-ACA dimer, etc. |
| Residual Solvents | Gas Chromatography (GC) | Headspace or direct injection method using an FID detector to measure residual organic solvents (e.g., acetone, methanol, ethanol) from the manufacturing process. |
| Loss on Drying | Thermogravimetric Analysis / Atmospheric Drying Method | Dry the sample at a specified temperature (e.g., 105 °C) until constant weight is achieved, then calculate the percentage weight loss to indicate moisture and volatile content. |
| Residue on Ignition (Ash Content) | High-Temperature Ignition Method | Ignite the sample at high temperature (approximately 700–800 °C) and weigh the residue to assess the total inorganic impurity content. |
| pH Value | pH Meter Method | Prepare an aqueous solution of a defined concentration and measure the pH using a calibrated pH meter to ensure compliance with pharmacopoeia specifications. |
| Specific Optical Rotation | Polarimetry | Measure the optical rotation of the aqueous solution at a specific wavelength (usually the sodium D-line, 589 nm) to evaluate optical purity. |
| Water Content | Karl Fischer Titration | Use volumetric or coulometric methods to specifically determine the water content, suitable for thermally unstable samples. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine residual levels of harmful elements such as lead, cadmium, mercury, and arsenic to ensure compliance with specified limits. |
