Manufacturing Quality Control of Tocopheryl acetate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | By comparing the infrared absorption spectrum of the sample with that of a reference standard, the molecular structure characteristic peaks are confirmed to be consistent, used for qualitative identification. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase column, methanol/water or acetonitrile/water as the mobile phase, and a UV detector (e.g., 284 nm) for quantitative analysis of the main component content. |
| Related Substances/Impurities | High-Performance Liquid Chromatography (HPLC) | Separating the main peak and impurity peaks using a gradient elution program, and calculating the relative content of each impurity by area normalization or external standard method. |
| Drying Loss | Drying Method (105°C, constant weight) | The sample is dried at a specified temperature until constant weight, and the percentage of mass loss is calculated to evaluate the content of moisture and volatile substances. |
| Residue on Ignition | High-Temperature Ashing (600–800°C) | The sample is incinerated at high temperature and the residual inorganic material is weighed to assess the total amount of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | Determining the residual levels of harmful heavy metals such as lead, arsenic, cadmium, and mercury using atomic absorption or inductively coupled plasma mass spectrometry. |
| Acid Value | Acid-Base Titration | Titration of free acids with potassium hydroxide ethanol solution, using phenolphthalein as an indicator, to evaluate esterification degree and hydrolysis product content. |
| Peroxide Value | Iodometric Method | Using potassium iodide to react with peroxides and release iodine, which is then titrated with sodium thiosulfate, to assess the degree of oxidation and deterioration. |
| Specific Rotation | Optical Rotatory Dispersion Measurement | Measuring the optical rotation of a solution of specific concentration under the sodium D line, used to determine optical purity and configuration consistency (if applicable). |
| Solution Clarity and Color | Visual Colorimetry or Spectrophotometry | Comparing with standard color solutions or measuring absorbance at a specific wavelength to evaluate product appearance quality and degradation status. |
