Industrial Applications of 2251-50-5
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of fluorinated pharmaceutical intermediates for antitumor, antiviral, and central nervous system drugs | Used as an acylating agent in nucleophilic substitution reactions to introduce the pentafluorobenzoyl group |
| Agrochemicals | Synthesis of fluorinated active ingredients, including herbicides and insecticides | Condensed with amines or alcohols to construct pesticide molecular frameworks containing the pentafluorophenyl group |
| Materials Science | Preparation of high-performance fluorinated polymers, liquid crystal materials, and organic electronic materials | Applied in Friedel–Crafts acylation or condensation with phenols/amines to introduce the strongly electron-withdrawing pentafluorobenzoyl group, thereby tuning optoelectronic properties |
| Organic Synthesis | Highly reactive acid chloride reagent for C–C or C–N bond formation | Reacted with arenes, heterocyclic compounds, or nucleophiles under inert atmosphere to yield corresponding ketones or amide derivatives |
Manufacturing Quality Control of 2251-50-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration where iodine is generated coulometrically to react stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., residual HCl, benzoic acid) using standardized sodium hydroxide and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after controlled high-temperature ashing at 500-600 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, based on absorption of characteristic atomic spectral lines. |
| Chloride Ion (Cl-) | Potentiometric Titration with AgNO3 | Titration using silver nitrate with a silver indicator electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against a white background under controlled lighting conditions. |
| Boiling Point | Capillary Boiling Point Determination | Measurement of temperature at which vapor pressure equals atmospheric pressure, using calibrated capillary apparatus. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface using a calibrated Abbe refractometer at specified temperature. |
| Density | Oscillating U-tube Densitometry | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the sample. |
| Non-Volatile Residue | Evaporation and Gravimetry | Weighing residue remaining after gentle evaporation of a fixed sample volume under nitrogen stream at controlled temperature. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and semi-quantitation of structurally related impurities based on retention time and mass spectral fragmentation patterns. |
