Manufacturing Quality Control of Methanedisulphonic acid
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Purity/Content Determination | High-Performance Liquid Chromatography (HPLC) | An reversed-phase C18 column is used, with water-organic solvent (e.g., methanol or acetonitrile) as the mobile phase. A UV detector (typically at 200–220 nm wavelength) is employed, and the content of methanedisulfonic acid is calculated using the external standard method or area normalization method. |
| Appearance | Visual Inspection Method | Observe the sample's color, physical state (e.g., white crystals or powder), and presence of foreign matter, in accordance with pharmacopoeia or enterprise standards. |
| pH Value | pH Meter Method | A 1% w/v aqueous solution of methanedisulfonic acid is prepared and its pH is measured at room temperature using a calibrated pH meter to determine whether it falls within the specified range (typically strongly acidic). |
| Loss on Drying | Gravimetric Drying Method | The sample is placed in a pre-weighed weighing bottle and dried at a specified temperature (e.g., 105°C) until constant weight is achieved. The percentage weight loss is calculated to evaluate moisture and volatile impurities. |
| Residue on Ignition / Sulfated Ash | High-Temperature Ignition Method | The sample is charred and then ignited at high temperature (e.g., 700–800°C) until constant weight. The remaining inorganic residue is weighed to assess the total inorganic impurities. |
| Related Substances (Impurities) | HPLC Gradient Elution Method | A gradient elution program is used to separate the main component from potential impurities (e.g., unreacted starting materials, by-products, degradation products). Impurity levels are controlled by comparing peak areas, often with LC-MS for qualitative confirmation. |
| Water Content | Karl Fischer Titration | Karl Fischer reagent reacts quantitatively with water in the sample. The water content is determined by coulometric or volumetric titration, suitable for sulfonic acid compounds sensitive to moisture. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, heavy metal contents such as lead, arsenic, cadmium, and mercury are determined using AAS or ICP-MS to ensure compliance with safety limits. |
