| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | The infrared absorption spectrum of the sample is measured and compared with the standard spectrum to confirm the presence of characteristic functional groups of benzo[f]furan-6-carboxylic acid, such as carboxyl group and furan ring. |
| Identification Test | Proton Nuclear Magnetic Resonance (¹H NMR) | ¹H NMR is used to analyze the chemical shift, coupling constants, and integral area of hydrogen atoms in the sample, verifying whether the molecular structure matches the expected structure of benzo[f]furan-6-carboxylic acid. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column, with an appropriate ratio of methanol/acetonitrile-water (with a small amount of acid to adjust pH) as the mobile phase, and a UV detector (typically at 254 nm or the maximum absorption wavelength) to quantitatively determine the content of the main component. |
| Related Substances (Impurity) Testing | High-Performance Liquid Chromatography (HPLC) | Use similar or optimized chromatographic conditions as for content determination to separate and detect possible process impurities and degradation products. The limit control is performed by area normalization method or by using a reference substance with correction factor. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Drying at Constant Temperature | Dry the sample at a specified temperature (e.g., 105°C) until constant weight, and measure the mass loss to evaluate the content of moisture and volatile substances. |
| Residue on Ignition | High-Temperature Incineration Method | The sample is carbonized and then incinerated at 700–800°C in a muffle furnace. The mass of the residual inorganic material is weighed to control the total amount of inorganic impurities. |
| Residual Solvents | Gas Chromatography (GC) | Using headspace injection or direct injection, the residual organic solvents (such as methanol, dichloromethane, DMF, etc.) during synthesis or purification are detected by capillary chromatographic columns and a flame ionization detector (FID). |
| pH Value | pH Meter Measurement | Prepare a solution of the sample at a certain concentration (e.g., 1% w/v), and use a calibrated pH meter to measure its pH value, reflecting the dissociation characteristics of the carboxylic acid and possible acidic or basic impurities. |
| Melting Point | Capillary Melting Point Determination | Use a melting point apparatus to determine the temperature range from initial melting to complete melting, serving as a physical constant for identification and preliminary purity assessment. |
