| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Assay | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with water or methanol-water as the mobile phase, and detection by refractive index or evaporative light scattering detector to quantitatively analyze the content of D-pinitol. This method offers high sensitivity and good reproducibility, suitable for purity and main component analysis. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Employs ¹H-NMR and ¹³C-NMR to identify the structure of D-pinitol. Characteristic peak positions and coupling constants are used to confirm stereochemistry and functional groups, making it an authoritative technique for structural elucidation. |
| Purity and Impurity Analysis | High-Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS) | Combines the separation capability of HPLC with the structural identification power of MS to detect organic impurities, degradation products, or homologs in D-pinitol, enhancing the accuracy of impurity identification. |
| Moisture Content | Karl Fischer Titration | Determines water content based on the quantitative reaction of iodine and sulfur dioxide with water in an anhydrous environment. Suitable for moisture control in hygroscopic substances like D-pinitol. |
| Sulfated Ash / Residue on Ignition | Residue on Ignition Test | Involves high-temperature incineration of the sample until constant weight is achieved, measuring the amount of non-volatile inorganic residue. Used to assess levels of inorganic impurities. |
| Heavy Metals Test | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Measures residual levels of heavy metal elements such as lead, arsenic, cadmium, and mercury to ensure compliance with safety standards for pharmaceutical or food additive use. |
| Specific Optical Rotation | Polarimetry | Leverages the optical activity of D-pinitol by measuring its specific optical rotation under sodium light to verify stereochemical configuration and purity. A key physical constant test for chiral compounds. |
| Melting Point | Melting Point Apparatus | Determines the temperature at which D-pinitol transitions from solid to liquid upon heating, used to assess purity and crystalline form consistency. Pure compounds exhibit a sharp and defined melting point. |
