Industrial Applications of Ethylzinc bromide, 0.50 M in THF
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Organozinc reagents for carbon–carbon bond formation, e.g., Reformatsky and Negishi coupling reactions | Acts as a nucleophile in cross-coupling reactions with aldehydes, ketones, acyl chlorides, or organic halides (e.g., aryl/vinyl halides) under palladium or nickel catalysis; or adds to carbonyl compounds via enolization intermediates |
| Pharmaceutical R&D | Intermediate for chiral drug molecules, e.g., β-hydroxy ester structures | Undergoes asymmetric Reformatsky-type addition with aldehyde substrates under anhydrous, low-temperature conditions, typically in combination with chiral ligands (e.g., DAIB) |
| Materials Science | Precursor for organometallic polymers and functionalized conjugated polymers | Participates as a bifunctional zinc reagent in step-growth polymerization or catalytic coupling with dihaloarenes to construct π-conjugated backbones |
| Agrochemical Chemistry | Synthesis of zinc-containing heterocycles or alkylated intermediates for insecticide and fungicide structural modification | Undergoes Zn–X exchange with heterocyclic compounds bearing reactive halogens (e.g., 2-chloropyrimidine), followed by further functional group transformations |
Manufacturing Quality Control of Ethylzinc bromide, 0.50 M in THF
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (ZnC2H5Br content) | Gas Chromatography (GC) with FID detector | Quantifies ethyl bromide and related organozinc species by retention time and peak area against calibrated standards. |
| Residual Solvent (e.g., THF, diethyl ether) | Gas Chromatography (GC) with FID or TCD | Separates and quantifies volatile solvents based on volatility and detector response relative to internal standard. |
| Water Content | Karl Fischer Titration (coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Free Bromine (Br2) | Iodometric Titration | Oxidation of iodide to iodine by free bromine, followed by thiosulfate titration of liberated iodine. |
| Zinc Content | ICP-OES | Atomization and excitation of zinc in argon plasma; quantification via characteristic emission intensity at 213.86 nm. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Ionization in plasma followed by mass-selective detection at isotopic masses; provides ultratrace multi-element quantification. |
| Acidity (as HBr) | Acid-Base Titration with NaOH and potentiometric endpoint | Neutralization of acidic impurities (e.g., HBr) using standardized sodium hydroxide; endpoint detected by pH change. |
| Color | Visual Comparison or APHA Color Scale | Comparison of sample solution color against platinum-cobalt standard solutions under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Heating sample to high temperature to volatilize organics; residue weight reflects inorganic ash content. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on ion-exchange column; quantified by conductivity response relative to calibration curve. |
| Diethyl Zinc Impurity | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by selective detection of diethyl zinc fragment ions (e.g., m/z 122, 91) for identification and quantification. |
| Peroxide Value | Ferrous Oxidation-Xylenol Orange (FOX) Assay | Peroxides oxidize Fe2+ to Fe3+, which complexes with xylenol orange to yield colored product measured spectrophotometrically. |
