Manufacturing Quality Control of 3,5-Difluorophenol
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and state (usually white to off-white crystalline or powder) under natural light or standard illumination to determine if it meets specifications. |
| Melting Point | Capillary Melting Point Determination | Fill the sample into a melting point capillary tube, slowly heat it using a melting point apparatus, and record the temperature range from initial melting to complete melting, comparing it with the standard value (approximately 63–65 °C). |
| Purity (Content) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 chromatographic column, with methanol-water or acetonitrile-water as the mobile phase, and detect with a UV detector (e.g., at 254 nm). Calculate the main component content using external standard method or area normalization method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use the same conditions as for purity determination or optimize gradient elution programs to separate and quantify potential impurities (such as unreacted raw materials, by-products, degradation products), typically requiring individual impurities ≤0.1% and total impurities ≤0.5%. |
| Moisture | Karl Fischer Titration | Determine the moisture content using a Karl Fischer titrator, which quantitatively reacts iodine with sulfur dioxide in pyridine/imidazole to react with water. Control generally ≤0.5%. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace injection or direct injection, with polar or non-polar capillary columns and FID detection, to determine residual organic solvents (such as toluene, dichloromethane, etc.) from the production process, meeting the ICH Q3C limits. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After acid digestion of the sample, determine the total amount of heavy metals such as lead, cadmium, mercury, and arsenic using AAS or ICP-MS. The limit is usually ≤10 ppm. |
| pH Value (Solution) | pH Meter Measurement | Prepare a solution of 3,5-difluorophenol (e.g., 1%) and measure its pH value using a calibrated pH meter to assess its acidity or alkalinity and ensure it meets requirements. |
