Industrial Applications of Folcisteine
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Antibacterial agent for studying bacterial resistance mechanisms | Used in laboratory synthesis and biological activity testing |
| Research | Tool compound in antibiotic research | Applied in microbial culture and inhibition assays |
| Chemical Reagents | Intermediate or reference standard in organic synthesis | Used for purification, calibration, and reaction controls |
Manufacturing Quality Control of Folcisteine
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Thin-Layer Chromatography (TLC) | Qualitative identification by comparing the spot positions (Rf values) and color development characteristics of the sample and reference substance after development on a silica gel plate. |
| Infrared Spectroscopy (IR) | Confirm consistency of functional group structures by comparing characteristic peaks in the infrared absorption spectrum. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Quantitative analysis of the active ingredient using a reversed-phase C18 column, with methanol-water or acetonitrile-water as the mobile phase and a UV detector (e.g., 270–280 nm). |
| Ultraviolet-Visible Spectrophotometry (UV-Vis) | Determine the content of total flavonoids or specific components using the maximum absorbance at a specific wavelength and a calibration curve. | |
| Related Substances / Impurity Testing | High-Performance Liquid Chromatography (HPLC) | Use a gradient elution program to separate and detect impurity peaks other than the main peak, assessing purity and degradation products. |
| Moisture | Loss on Drying or Karl Fischer Titration | Loss on drying is suitable for heat-stable samples; Karl Fischer method is more accurate and suitable for trace moisture determination. |
| Residue on Ignition (Ash) | Sulfated Ash Method | Weight of inorganic residue remaining after high-temperature incineration of the sample, expressed as a percentage of the original sample, used to evaluate inorganic impurity content. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Determine whether levels of heavy metal elements such as lead, cadmium, arsenic, mercury, and copper comply with pharmacopoeial limits. |
| Pesticide Residues | Gas Chromatography-Mass Spectrometry (GC-MS) | High-sensitivity qualitative and quantitative analysis of pesticide residues such as organochlorines and organophosphates. |
| Microbial Limits | Plate Count Method, Membrane Filtration Method | Test total aerobic microbial count, total mold and yeast count, and specified microorganisms (e.g., Escherichia coli) according to the requirements of the Chinese Pharmacopoeia. |
