Manufacturing Quality Control of Ethane,1,1'-Oxybis〔2-(2-bromoethoxy)-
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210 nm based on peak area comparison to reference standard. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., THF, DCM) by gas chromatography with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in a methanol-based reagent. |
| Acid Value | Acid-Base Titration | Determines acidic impurities by titrating with standardized KOH solution in isopropanol using phenolphthalein indicator. |
| Bromine Content | Potentiometric Titration with AgNO3 | Quantifies total bromide by argentometric titration using silver nitrate and potentiometric endpoint detection. |
| Color | APHA Color Scale | Evaluates visual color intensity by comparing sample solution to platinum-cobalt standard solutions under controlled lighting. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of particulates or phase separation in a clear glass container against white background. |
| Heavy Metals | ICP-OES | Simultaneously quantifies trace metals (e.g., Pb, Cd, Ni, Fe) after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Residual Catalyst (Pd) | ICP-MS | Detects palladium residues at sub-pptr levels following microwave-assisted digestion using inductively coupled plasma mass spectrometry. |
| Average Molecular Weight | GPC/SEC | Determines molecular weight distribution relative to PEG standards using gel permeation chromatography with RI detection. |
| Hydroxyl Number | Acetylation Titration | Measures terminal OH groups by acetylating with acetic anhydride, then back-titrating unreacted anhydride with NaOH. |
| pH (1% w/v aqueous solution) | pH Meter Measurement | Determines acidity/basicity of aqueous solution using calibrated pH electrode and standard buffer calibration. |
