Manufacturing Quality Control of Azelaic acid
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Scan the sample and reference standard under identical conditions, then compare characteristic absorption peaks (e.g., carboxyl, C-H) to confirm structural consistency. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (typically set at around 210 nm), and methanol-water or buffered solution as mobile phase. Quantify azelaic acid content using external or internal standard method. |
| Related Substances / Impurities | High-Performance Liquid Chromatography (HPLC) | Using the same HPLC system, separate azelaic acid from potential organic impurities (such as starting materials, intermediates, or degradation products) via gradient elution. Calculate individual impurity peak areas and evaluate against specified limits. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved. Calculate the content of moisture and volatile components based on weight loss. |
| Sulfated Ash | Sulfated Residue Method | Treat the sample with sulfuric acid, then incinerate at high temperature. Weigh the residue to determine the total amount of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Digest the sample and measure the levels of toxic elements such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmacopoeial or regulatory limits. |
| Solution Clarity and Color | Visual Comparison Method | Prepare a solution of the sample at a defined concentration and compare it visually with standard color solutions to assess clarity and whether color falls within acceptable limits. |
| pH Value | pH Meter Method | Dissolve azelaic acid in water or a suitable solvent (e.g., water-ethanol mixture), and measure the pH using a calibrated pH meter to evaluate its acidity. |
