Industrial Applications of BENZENE (13C6)
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Isotope-labeled tracers for drug metabolism and pharmacokinetics (DMPK) studies and elucidation of biotransformation pathways | Used as a stable isotope internal standard or starting material in synthetic routes; incorporated into target molecules via palladium-catalyzed cross-coupling, electrophilic substitution, and other reactions to achieve site-specific 13C labeling |
| Analytical Testing | Internal standard for high-performance liquid chromatography–mass spectrometry (HPLC-MS) and gas chromatography–mass spectrometry (GC-MS) quantification of benzene and its metabolites | Coinjected with test samples; enables isotope dilution mass spectrometry (IDMS) quantification by exploiting the mass-to-charge ratio difference (m/z +6) relative to naturally abundant benzene |
| Environmental Science | Tracer for source apportionment of environmental benzene contamination and investigation of biodegradation mechanisms | Added to soil/water microcosm systems; 13C flow to CO2, microbial biomass, or intermediate metabolites is tracked using 13C-NMR or isotope ratio mass spectrometry (IRMS) |
| Materials Science | Precursor for isotopically engineered synthesis of carbon-based functional materials (e.g., graphene, carbon nanotubes) | Thermally decomposed via catalytic cracking or chemical vapor deposition (CVD) to generate 13C-enriched carbon feedstock for preparing two-dimensional carbon materials with controlled isotopic purity |
Manufacturing Quality Control of BENZENE (13C6)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Isotopic Purity (13C6) | GC-MS or LC-MS | Measures relative abundance of 13C6 isotopologue vs. other carbon isotopologues using mass spectral fragmentation and ion intensity ratios. |
| Chemical Purity | GC-FID | Quantifies benzene-13C6 and impurities (e.g., residual C12-benzene, toluene) by retention time and peak area integration. |
| Water Content | Karl Fischer Titration | Determines water via stoichiometric reaction between iodine, sulfur dioxide, and water in a methanol-based reagent. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic impurities (e.g., acetone, methanol, DCM) using calibrated headspace or direct injection GC. |
| Acidity (as H+) | Acid-Base Titration | Neutralizes acidic impurities with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporates sample under controlled conditions and weighs residue to assess particulate or high-boiling contaminants. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace metal concentrations by atomizing and ionizing the sample, then measuring elemental mass-to-charge ratios. |
| Chloride Ion | Ion Chromatography | Separates and quantifies Cl- anions using anion-exchange column and suppressed conductivity detection. |
| Density | Digital Density Meter | Measures mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Digital Refractometer | Determines refractive index based on critical angle of total internal reflection of light through the sample. |
| Color (APHA) | Visual Comparison or Spectrophotometer | Evaluates yellowness/browning by comparing to platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Residual Catalyst (e.g., Pd, Ni) | ICP-OES | Quantifies catalytic metal residues after acid digestion by measuring characteristic atomic emission lines. |
