High-purity reference materials for robust method development, calibration, and quality control in food, environmental, and industrial residue analysis.

Overview

Dodecyl-4-iodo-benzene (p-iodododecylbenzene) is an aromatic iodide featuring a long-chain alkyl substituent. Its hydrophobic character and iodine functionality make it relevant as a synthetic intermediate and as a target or potential interference in advanced analytical workflows. HPC Standards provides traceable reference materials to support accurate identification, quantification, and method validation.

Our reference materials are produced and tested according to international quality requirements, enabling laboratories to achieve reliable results and regulatory-grade data integrity.

Chemical Identity and Properties

Empirical formula: C18H29I. Structural class: para-iodoalkylbenzene (aromatic iodide). Typical physicochemical profile includes low aqueous solubility, strong hydrophobicity, and good solubility in common organic solvents used in chromatography. The iodine substituent facilitates selective detection with mass spectrometry and provides characteristic isotopic patterns.

These features influence chromatographic behavior, extraction efficiency, and ionization, and should be considered when optimizing analytical methods.

Uses and Application Context

- Reference for method development and system suitability in GC-MS/LC-MS workflows involving halogenated aromatics and long-chain hydrophobes.

- Calibration and recovery studies in residue analysis of complex matrices (e.g., environmental samples, industrial process streams, and materials-related investigations).

- Selectivity checks to evaluate potential interferences in multi-residue screens.

Regulatory Considerations

While Dodecyl-4-iodo-benzene is not a commonly regulated food pesticide residue, laboratories may encounter it in environmental or industrial monitoring programs and non-target screening. Reference materials support defensible data for compliance-driven reporting, method validation (e.g., selectivity, linearity, accuracy), and internal quality control aligned with international guidelines.

Monitoring and Residue Analysis

- Matrices: water, sediments, soils, industrial effluents, and extracts from materials or products depending on study design.

- Targeted and non-targeted approaches: used as a check compound to assess extraction efficiency, matrix effects, and instrument response for hydrophobic, halogenated analytes.

- Quality markers: retention time stability, qualifier/quantifier ion ratios, response factors, and recovery within predefined acceptance criteria.

Human Toxicity and Exposure

Data for Dodecyl-4-iodo-benzene may be limited; as a hydrophobic aromatic iodide, it should be handled as potentially harmful on skin and eye contact and if inhaled or ingested. Implement appropriate engineering controls and PPE, and consult the Safety Data Sheet (SDS) for hazard statements and first-aid measures. Avoid aerosol formation and prolonged exposure.

Environmental Impact

Hydrophobic, halogenated aromatics may exhibit persistence and bioaccumulation potential. Prevent releases to the environment, manage waste according to local regulations, and document disposal routes. Environmental testing programs should consider sorption to solids and potential partitioning into organic phases.

Safety Measures and Handling

- Use in a fume hood with laboratory coat, safety glasses, and appropriate gloves.

- Avoid ignition sources; store away from strong oxidizers and incompatible materials.

- Follow SDS guidance for spill response, disposal, and transport.

Analytical Methods and Instrument Compatibility

- Chromatography: LC-MS/MS or GC-MS/MS depending on volatility; typical use in reversed-phase LC or non-polar GC phases.

- Detection: ESI/APCI (LC) or EI/CI (GC); iodine aids mass spectral specificity and confirmation via characteristic fragments and isotope patterns.

- Sample prep: non-polar extraction/cleanup strategies; evaluate matrix effects and recovery using appropriate internal or surrogate standards.
