Manufacturing Quality Control of Phloroglucinol dihydrate
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Appearance | Visual and Solubility Examination | Observe the color and physical state (usually white or nearly white crystalline powder) of the sample, and check its solubility in water and ethanol. |
| Ultraviolet-Visible Spectrophotometry (UV-Vis) | Use the characteristic absorption peak of resorcinol at a specific wavelength (e.g., around 275 nm) for qualitative identification. | |
| Infrared Spectroscopy (IR) | Prepare a KBr pellet with the sample and measure the infrared spectrum. Compare it with the standard spectrum to confirm consistency in functional group structure. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 column with methanol-water or buffer solution as the mobile phase, detect using a UV detector, and calculate the content using the external standard method. |
| Ultraviolet Spectrophotometry (UV) | Determine the absorbance at the maximum absorption wavelength and quantitatively analyze the concentration of resorcinol based on a standard curve. | |
| Moisture | Karl Fischer Titration | Precisely determine the total amount of crystalline water and adsorbed water in the sample, suitable for moisture control in hygroscopic compounds. |
| Dry Loss | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is reached, calculate the loss in weight, and assess the moisture and volatile impurity content. |
| Residue on Ignition | Residue on Ignition Test | Heat the sample at a high temperature (around 600–800°C), weigh the residue, and evaluate the content of inorganic impurities. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate the main component and impurities using gradient or isocratic elution, detect them, and limit related degradation products or by-products. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Dissolve the sample and determine the content of heavy metals such as lead, cadmium, and mercury, ensuring compliance with pharmacopoeia limits. |
| Chlorides, Sulfates | Turbidimetry | Follow the method described in the Chinese Pharmacopoeia, compare the turbidity with that of standard solutions to control inorganic anion impurities. |
| Microbial Limits | Microbial Limits Test | Perform tests for total aerobic microbial count, mold and yeast count, and control organisms (e.g., Escherichia coli) according to pharmacopoeia requirements. |
