| Industry | Application | Process |
|---|---|---|
| Analytical Chemistry | Used as a precipitating agent for separation and determination of alkali metal ions, such as potassium (K⁺) | Add tetrabutylammonium tetraphenylborate to an aqueous solution containing potassium ions to form insoluble potassium tetraphenylborate precipitate; quantify via filtration and gravimetric analysis |
| Organic Synthesis | Used as a phase-transfer catalyst or ion-pairing reagent | Facilitates anion transfer from the aqueous phase to the organic phase in biphasic reaction systems, enhancing reaction rate and selectivity |
| Materials Science | Used in the preparation of ionic liquids or functionalized material precursors | Reacted with other ion-exchange resins or metal salts to construct composite materials with tailored electrochemical properties |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~254 nm, comparing peak area against a certified reference standard. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration based on the reaction of iodine with water in anhydrous methanol/pyridine medium; measures trace water content precisely. |
| Residual Solvents (e.g., THF, MeOH) | GC-FID | Separation and quantification of volatile organic solvents by gas chromatography with flame ionization detection using calibrated standards. |
| Inorganic Anions (Cl⁻, SO₄²⁻) | Ion Chromatography (IC) | Separation of ionic species on an anion-exchange column with suppressed conductivity detection; quantifies common counterion impurities. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element trace metal quantification via inductively coupled plasma mass spectrometry after acid digestion and matrix-matched calibration. |
| Residue on Ignition (ROI) | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after controlled high-temperature ashing (550–600 °C) and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection via optical observation of solid-to-liquid phase change under controlled heating rate (e.g., 1–2 °C/min). |
| Appearance and Color | Visual Inspection & APHA Color Scale | Subjective assessment of physical state (crystalline powder) and color intensity compared to standardized platinum-cobalt solutions. |
| Specific Optical Rotation | [α]D (Polarimetry) | Measurement of rotation of plane-polarized light at 589 nm to confirm chiral integrity and absence of racemization (if applicable per synthesis route). |
| Organic Impurities (Related Substances) | HPLC-UV/DAD | Identification and quantification of structurally related degradation products or synthetic intermediates using gradient HPLC with diode-array detection. |
| pH of Aqueous Suspension | pH Meter (1% w/v suspension in water) | Electrochemical measurement of hydrogen ion activity in a saturated aqueous suspension to assess hydrolytic stability and acid/base impurity levels. |
