Manufacturing Quality Control of Diethyl cromoglycate
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with the standard spectrum to confirm characteristic functional groups and molecular structure of disodium cromoglycate. |
| High-Performance Liquid Chromatography (HPLC) | Compare the retention time of the main peak of the test sample with that of the reference substance under specific chromatographic conditions for qualitative identification. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column, with mobile phases such as methanol-water or acetonitrile-buffer salt systems, and UV detection (typically at 254 nm or 320 nm). Quantify disodium cromoglycate using the external standard method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Employ gradient or isocratic elution programs to separate and detect potential process impurities and degradation products. Quantification is typically performed using the area normalization method or self-control method. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Temperature Drying at Atmospheric Pressure | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, measuring mass loss to assess moisture and volatile content. |
| Residual Ash | High-Temperature Incineration Method | Char the sample, then incinerate at 700–800°C, weigh the inorganic residue to control the limit of inorganic impurities. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace injection or direct injection with FID detection to identify and quantify organic solvents (such as ethanol, acetone, dichloromethane) potentially residual from manufacturing processes, in accordance with ICH Q3C guidelines. |
| pH Value | pH Meter Method | Prepare an aqueous solution of a specified concentration (e.g., 1%), then measure the pH using a calibrated pH meter to ensure it falls within the required range (usually close to neutral). |
| Appearance and Physical Characteristics | Visual Inspection | Observe the sample’s color, physical state (should be a white or off-white crystalline powder), odor, and other visual attributes to match pharmacopeial descriptions. |
