Manufacturing Quality Control of J acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and state of the sample under natural light or standard illumination to determine if it is a powdery or crystalline substance ranging from grayish-brown to dark brown, and check for impurities. |
| Purity (Main Content) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (usually set at 254 nm or according to the maximum absorption wavelength). Compare with a reference standard to calculate the content of J-acid. The mobile phase is usually a gradient or isocratic elution of methanol and buffer solution (e.g., phosphate buffer). |
| Melting Point | Capillary Melting Point Method | Fill the dried sample into a capillary tube and gradually heat it in a melting point apparatus. Record the initial and final melting temperatures to assess purity and consistency. The melting point of J-acid is approximately above 300°C (may be accompanied by decomposition). |
| Moisture Content | Karl Fischer Titration | Use electrochemical titration to determine the moisture content in the sample. It is suitable for measuring trace amounts of water and provides accurate and reliable results. |
| Ignition Residue (Sulfate Ash) | Gravimetric Method | Heat the sample to constant weight at high temperature. The residue mainly consists of inorganic sulfates. Weigh the residue to calculate the percentage of ash, reflecting the content of inorganic impurities. |
| pH Value | pH Meter Measurement | Dissolve a certain amount of J-acid in water or a specified solvent, then measure the pH value using a calibrated pH meter to evaluate its acidity or alkalinity. |
| Heavy Metal Content | Atomic Absorption Spectrometry (AAS) or ICP-MS | Digest the sample and then use atomic absorption spectrometry or inductively coupled plasma mass spectrometry to determine the levels of heavy metals such as lead, arsenic, mercury, and cadmium, ensuring compliance with safety standards. |
| Organic Impurities (e.g., Residual Intermediates) | Thin Layer Chromatography (TLC) or HPLC | TLC is simple and fast; compare the number and position of spots after development and visualization. HPLC can quantitatively analyze by-products or unreacted raw materials. |
| Solubility | Solubility Test | Take a small amount of the sample and add it to solvents such as water or ethanol, shake, and observe the dissolution condition to determine its solubility in different solvents. |
