Manufacturing Quality Control of 1,2,3,4-Butanetetracarboxylic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity/Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 chromatographic column, water-organic solvent (such as methanol or acetonitrile) as the mobile phase, and a UV detector (typically at 200–220 nm), with external standard quantification to determine the content of the main component and total impurities. |
| Appearance | Visual Inspection/Colorimetry | Observe the color and physical state of the sample (should be white to off-white crystalline powder), and compare with standard color solutions if necessary. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, and calculate the percentage of weight loss to assess moisture and volatile substance content. |
| Melting Point | Capillary Melting Point Method or DSC | Use a melting point apparatus or differential scanning calorimeter (DSC) to determine the melting temperature range, verifying its purity and polymorphic consistency. |
| pH Value | pH Meter Method | Prepare a solution of a certain concentration (e.g., 1% w/v) and measure its acidity or alkalinity using a calibrated pH meter, reflecting the content of free acid. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, heavy metals such as lead, arsenic, cadmium, and mercury are determined by AAS or inductively coupled plasma mass spectrometry (ICP-MS). |
| Residual Solvents | Gas Chromatography (GC) | Use headspace injection or direct injection, with polar or non-polar capillary columns and a FID detector, to determine residual organic solvents (such as ethanol, acetone, etc.) from synthesis or purification processes. |
| Ignited Residue (Sulfated Ash) | High-Temperature Ignition Method | Char the sample and then ignite it in a high-temperature furnace at 700–800°C until constant weight is reached. Weigh the residue to assess the content of inorganic impurities. |
| Related Substances (Impurities) | HPLC-UV or LC-MS | Use gradient elution HPLC combined with UV or mass spectrometry detection to separate and identify process impurities and degradation products, ensuring that the total impurity level meets the limit requirements. |
