Manufacturing Quality Control of Itaconic acid
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Purity/Content Determination | High-Performance Liquid Chromatography (HPLC) | Reverse-phase C18 column is used, with phosphate buffer-methanol or acetonitrile as the mobile phase. The itaconic acid peak area is detected by a UV detector (typically around 210 nm). Quantification is performed using external or internal standard methods, offering high accuracy and good reproducibility. |
| Volumetric Titration | Utilizes the carboxyl groups of itaconic acid to perform acid-base titration with a standard sodium hydroxide solution. The total acid content is calculated based on the amount of alkali consumed. Simple to operate but with lower specificity, suitable for rough determination. | |
| Appearance | Visual Inspection | Observe the sample’s color and physical state (should be white crystals or crystalline powder) under natural or standard lighting, ensuring no visible impurities. |
| Melting Point | Melting Point Determination | Determine the melting temperature range of the sample using a melting point apparatus or capillary method (theoretical melting point of itaconic acid is about 162–165 °C), to assess purity and crystal form consistency. |
| pH Value | pH Meter Method | Prepare an aqueous solution of a certain concentration (e.g., 1% w/v) and measure its pH using a calibrated pH meter (typically between 2.0–3.0), reflecting acidity and the influence of impurities. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Ordinary Drying Method | Dry the sample at a specified temperature (e.g., 105 °C) until constant weight is achieved, then calculate the percentage of mass loss to evaluate moisture and volatile impurities. |
| Sulfated Ash | High-Temperature Ashing | The sample is incinerated at high temperature (about 600–800 °C), and the residual inorganic matter is weighed to control the total content of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, determine the content of harmful heavy metal elements such as lead, arsenic, cadmium, and mercury, ensuring compliance with pharmacopoeia or industrial standard limits. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Gradient or isocratic elution is used to separate the main component from potential impurities (such as maleic acid, citric acid, and other by-products). Impurity levels are calculated by peak area normalization or with correction factors. |
| Water Content | Karl Fischer Titration | Use highly specific Karl Fischer reagent to titrate the water content in the sample. Suitable for accurate determination of trace moisture, especially reliable for thermally unstable samples. |
