| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of antitumor agents | Used as an intermediate in synthetic reactions, including esterification and amidation, to construct the target molecular structure. |
| Agrochemicals | Herbicide production | Applied in the preparation of certain herbicide precursors, primarily via transesterification and related reaction pathways. |
| Materials Science | Preparation of specialty-performance polymers | Employed as a monomer or modifier in polymer synthesis to enhance thermal stability or other material properties. |
| Fine Chemicals | Development of novel functional chemicals | Utilized as a fundamental raw material for synthesizing various functional compounds, such as surfactants and fluorescent whitening agents. |
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection / Observation Method | Observe the color, physical state, and presence of visible impurities under natural or standard lighting. Typically appears as white to off-white powder. |
| Assay (Content Determination) | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with acetonitrile/water or buffer-containing mobile phases (e.g., phosphate buffers) under isocratic or gradient elution. The analyte is quantified using a UV detector (commonly set at 220–254 nm). Purity is calculated via external or internal standard method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Same as above; optimized chromatographic conditions are used to separate and detect potential impurities such as synthesis intermediates, by-products, or degradation products. Individual impurity levels are assessed using peak area normalization or reference standard (external standard) methods. |
| Residual Solvents | Gas Chromatography (GC) | Analyzes residual organic solvents (e.g., dichloromethane, ethanol, ethyl acetate) based on manufacturing processes, using headspace or direct solution injection with FID detection. Complies with ICH Q3C guidelines. |
| Water Content (Moisture) | Karl Fischer Titration | Determines water content precisely using an automatic moisture analyzer, either by coulometric or volumetric method. Suitable for compounds sensitive to moisture. |
| Melting Point | Melting Point Determination (Capillary Method or DSC) | The melting temperature range is measured using a melting point apparatus; Differential Scanning Calorimetry (DSC) provides more accurate determination of melting point and crystalline characteristics. |
| Infrared Spectrum (IR) | Fourier Transform Infrared Spectroscopy (FT-IR) | Infrared absorption spectrum is obtained by pressing the sample with KBr or using an ATR accessory. The resulting spectrum is compared with a reference spectrum to confirm structural consistency of functional groups. |
| Nuclear Magnetic Resonance (NMR) | ¹H-NMR and ¹⁹F-NMR | Dissolve sample in deuterated solvent (e.g., DMSO-d6); molecular structure is verified using proton and fluorine NMR, particularly confirming substitution patterns of trifluoroethoxy and phenyl groups. |
| Mass Consistency | Liquid Chromatography-Mass Spectrometry (LC-MS) | Used to confirm molecular ion peaks ([M-H]⁻ or [M+X]⁺), aiding in structural confirmation and identification of impurity structures. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Measures particle size distribution for active pharmaceutical ingredients intended for formulation, influencing solubility and bioavailability. |
| Residue on Ignition / Sulfated Ash | Gravimetric Method | The sample is ignited at high temperature and the residue is weighed to evaluate inorganic impurity content. |
| Heavy Metals | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | Determines residual toxic elements such as lead, cadmium, mercury, and arsenic, in compliance with pharmacopoeial standards or ICH Q3D elemental impurity limits. |
