Manufacturing Quality Control of 1,2-DISTEAROYL-RAC-GLYCEROL
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity | High-Performance Liquid Chromatography (HPLC) | Separates the sample using reversed-phase or normal-phase chromatographic columns, with UV or evaporative light scattering detection for quantitative determination of the main component, thereby assessing purity. |
| Fatty Acid Composition | Gas Chromatography (GC) | After methyl esterification of the sample, fatty acid methyl esters are separated using a capillary column and analyzed by FID detector to determine stearic acid content and impurity fatty acids. |
| Acid Value | Acid-Base Titration Method | Titrate free fatty acids in the sample with standardized potassium hydroxide solution, using phenolphthalein as indicator; calculate the milligrams of KOH consumed per gram of sample. |
| Hydroxyl Value | Acetylation Method + Acid-Base Titration | React the sample with acetic anhydride to form esters, then hydrolyze and titrate residual acid with KOH to determine hydroxyl group content, reflecting the proportion of unesterified hydroxyl groups. |
| Saponification Value | Saponification Titration Method | Subject the sample to saponification with excess KOH in ethanol under reflux, then back-titrate with standardized HCl solution to calculate the milligrams of KOH required per gram of sample for complete saponification. |
| Moisture Content | Karl Fischer Titration Method | Utilizes the stoichiometric reaction between iodine and sulfur dioxide in a pyridine/methanol system with water; moisture content is determined by potentiometric or visual endpoint detection. |
| Melting Point | Capillary Melting Point Determination Method | Load the sample into a melting point capillary tube and place it in a melting point apparatus; gradually heat and record the temperature range at which the solid completely melts. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, detect trace heavy metals such as lead, arsenic, cadmium, and mercury using atomic absorption spectrometry or inductively coupled plasma mass spectrometry. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Seal the sample and heat it to allow volatile solvents to enter the headspace; separate and quantify them using GC-FID or GC-MS, meeting ICH Q3C requirements. |
| Appearance and Color | Visual Color Comparison / Colorimeter | Visually compare or measure color using a colorimeter under standard lighting conditions (e.g., APHA or Gardner scale), assessing clarity and presence of foreign matter. |
