| Industry | Application | Process |
|---|---|---|
| Food Industry | Used as a sweetener and pH regulator | Produced via oxidation of glucose to glucaric acid, followed by neutralization with potassium hydroxide |
| Pharmaceutical Industry | Used in the synthesis of pharmaceutical intermediates | Prepared via chemical synthesis as a precursor for other organic compounds |
| Chemical Industry | Used as a chelating agent and stabilizer | Produced via organic synthesis for enhancing solution stability |
| Environmental Protection | Applied in wastewater treatment for heavy metal removal | Forms precipitates with heavy metal ions through chelation |
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and whether it is clumped under natural light or standard illumination to determine if the appearance meets specifications. |
| Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Compare the infrared spectrum of the sample with that of the reference standard; confirm consistency in characteristic functional group absorption peaks (e.g., carboxyl, hydroxyl) to verify authenticity. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase chromatographic column with UV or differential refractive index detection. Qualify components by retention time and quantify the main component based on peak area. |
| pH Value | pH Meter Method | Dissolve the sample in water to prepare a solution of specified concentration (e.g., 1% w/v), then measure the acidity or alkalinity using a calibrated pH meter. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at 105°C until constant weight, then calculate the moisture and volatile substance content based on mass loss. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Method | After high-temperature incineration of the sample, treat with sulfuric acid and determine the percentage by mass of residual inorganic matter to assess inorganic impurity levels. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine the concentrations of heavy metals such as lead, arsenic, cadmium, and mercury to ensure compliance with pharmacopeial or food safety limits. |
| Microbial Limits | Microbiological Culture Method | Perform total aerobic microbial count, mold and yeast enumeration, and control organism testing (e.g., Escherichia coli) according to pharmacopeial requirements. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate the main peak from impurity peaks using gradient or isocratic elution, calculate individual impurity peak areas to evaluate purity and impurity levels. |
| Specific Rotation | Polarimeter Method | Dissolve the sample in water and measure its optical rotation using a polarimeter under sodium light to verify optical purity and configurational consistency. |
