Industrial Applications of TETRAETHYLENE GLYCOL DI-P-TOSYLATE
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Used as a hydroxyl protecting reagent and crosslinking agent | Reacted with alcohols in inert solvents (e.g., THF, DCM) to introduce p-toluenesulfonyl groups, enabling selective protection or intermolecular/intramolecular bond formation |
| Polymer Chemistry | Used as a crosslinking modifier for thermosetting materials such as polyurethanes and epoxy resins | Undergoes substitution reactions with functional groups (e.g., polyols, amines) under thermal or catalytic conditions to form three-dimensional network structures |
| Pharmaceutical Intermediates | Used in synthesizing antiviral drugs and linkers for targeted drug delivery systems | Releases active pharmaceutical ingredients via controlled hydrolysis or nucleophilic substitution during solid-phase or solution-phase coupling reactions |
| Liquid Crystal Materials | Used as an end-group modifier for liquid crystal monomers to adjust phase transition temperature and dielectric anisotropy | Undergoes esterification with hydroxyl-containing liquid crystal core structures to introduce flexible ethylene glycol segments, optimizing molecular alignment performance |
Manufacturing Quality Control of TETRAETHYLENE GLYCOL DI-P-TOSYLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities by gradient HPLC-UV; identification based on retention time relative to reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., toluene, THF, methanol) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration | Titration with standardized potassium hydroxide solution using phenolphthalein indicator; measures free acidic impurities including residual p-toluenesulfonic acid. |
| Chloride Content | Ion Chromatography | Separation of chloride anions on an anion-exchange column with conductivity detection, quantified against chloride calibration standards. |
| Sulfate Content | Ion Chromatography | Anion-exchange separation followed by conductivity detection; quantifies sulfate from potential oxidation or hydrolysis byproducts. |
| Heavy Metals (Pb, Cd, Hg, Cr, As) | ICP-MS | Multi-element detection after microwave-assisted acid digestion; provides sub-ppq sensitivity and compliance with ICH Q3D guidelines. |
| Appearance | Visual Inspection | Assessment of color and clarity in solution (e.g., 5% w/v in acetonitrile) against water-white reference under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating crystallinity and absence of significant eutectic impurities. |
| Residue on Ignition | Gravimetric Analysis | Incineration at 600-700 C followed by weighing of non-volatile inorganic residue; reflects inorganic ash content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light at 20 C using sodium D-line; confirms chiral integrity and absence of racemization. |
