Manufacturing Quality Control of Diflunisal
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Confirm the consistency of molecular structural characteristic peaks by comparing the infrared absorption spectrum of the sample with that of a reference standard. |
| High-Performance Liquid Chromatography (HPLC) | Identify whether the main component is diflunisal by comparing the retention time with that of a reference standard. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Quantitative analysis using external standard or internal standard methods, with separation on a C18 column and detection via a UV detector (e.g., at 254 nm). |
| Related Substances | High-Performance Liquid Chromatography (HPLC) | Separate the main component from impurities using a gradient elution program; calculate impurity content by area normalization or self-reference method. |
| Loss on Drying | Drying Method (105°C to constant weight) | Dry the sample in a constant-temperature oven until constant weight is achieved, then calculate the percentage weight loss to control moisture and volatile substances. |
| Residue on Ignition | High-Temperature Ignition Method (600–800°C) | Ignite the sample at high temperature to ash it, then weigh the residual residue to assess the total amount of inorganic impurities. |
| Heavy Metals | Thioacetamide Method (Chinese Pharmacopoeia General Rule) | React the sample with thioacetamide under weakly acidic conditions to produce a color change, then compare with a standard lead solution to control heavy metal limits. |
| Residual Solvents | Gas Chromatography (GC, Headspace Injection) | Use a capillary column and FID detector to measure organic solvents potentially residual from the manufacturing process (e.g., methanol, ethanol, etc.). |
| pH Value | pH Meter Method | Prepare a solution of the sample at a specified concentration and directly measure its pH to ensure compliance with formulation stability requirements. |
| Melting Point | Capillary Melting Point Determination | Determine the temperature range from initial to complete melting of the sample, serving as a physical constant to verify purity and consistency. |
