Manufacturing Quality Control of Diglycolic acid
| Milestone | Common Testing Methods | Method Overview |
|---|---|---|
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase chromatography column, with phosphate buffer solution and organic solvent as the mobile phase, and a UV detector (e.g., 210 nm) for quantitative analysis of the main component. It offers high accuracy and good repeatability. |
| Related Substances Testing | HPLC (Gradient Elution) | Optimizes gradient programs to separate the main peak from impurity peaks, detecting possible by-products or degradation products, ensuring purity meets pharmacopoeia or company standards. |
| Moisture Content | Karl Fischer Titration | Utilizes the quantitative reaction between iodine and sulfur dioxide in a pyridine/methanol system with water, determining moisture content via potentiometric or visual endpoint. It accurately measures trace amounts of water in the sample. |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace or direct injection, with capillary columns for separation, and FID or MS detectors for quantification of residual organic solvents (e.g., methanol, ethanol), complying with ICH Q3C requirements. |
| pH Value | pH Meter Method | Prepares the sample as an aqueous solution of a certain concentration and directly measures the pH using a calibrated pH meter, reflecting its acidity or alkalinity, which affects stability and compatibility. |
| Ignited Residue | Weight Method | The sample is incinerated at high temperature (e.g., 600–800°C) until constant weight, and the mass of the remaining inorganic material is measured, assessing levels of inorganic impurities or metal catalyst residues. |
| Heavy Metal Testing | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, it detects toxic heavy metals such as lead, arsenic, cadmium, and mercury using atomic absorption or inductively coupled plasma mass spectrometry, ensuring compliance with safety limits. |
| Appearance and Physical Properties | Visual Color Comparison | Observes the color, crystalline form of solids, or clarity and color of solutions to preliminarily determine if the sample is contaminated or degraded. |
| Melting Point Determination | Capillary Melting Point Apparatus Method | Measures the temperature range at which a substance changes from solid to liquid, serving as a physical constant for identification and purity assessment. |
