High-purity hexadecane reference materials for GC-based fuel characterization, MOSH/MOAH studies, and environmental residue analysis – manufactured and quality-controlled by HPC Standards GmbH.
Overview
Hexadecane (IUPAC: hexadecane; also known as cetane) is a linear alkane hydrocarbon with the formula C16H34. It is a colorless liquid at ambient temperature with a high boiling point and very low volatility. Hexadecane is widely used as a performance reference in diesel combustion studies (cetane number) and as a retention index/calibration compound in gas chromatography.
Key identifiers: CAS 544-76-3; EC 208-878-9; PubChem CID 11006. Typical properties include: melting point ~18.2 °C, boiling point ~286.9 °C, density ~0.77 g/cm³ (20 °C), low vapor pressure (<0.1 mbar at 20 °C), high hydrophobicity (logP ~8.9), refractive index nD ~1.433.
Uses
- Fuel science: primary reference for cetane number determination and ignition quality benchmarking of diesel fuels.
- Chromatography: GC retention time/index marker and instrument performance check compound (GC-FID/GC-MS).
- QA/QC in environmental testing: spiking/fortification standard for method validation in water, soil, and sediment analyses.
- Food and packaging analytics: component within the MOSH (mineral oil saturated hydrocarbons) range for MOSH/MOAH method development and calibration.
Regulatory
Hexadecane is listed under major chemical inventories (e.g., EU/REACH substance inventories, CAS 544-76-3). It is not a pesticide active substance and has no MRLs in food commodities. Classification and labeling may include skin irritation warnings depending on jurisdiction (e.g., GHS signal word: Warning, H315). Always refer to the local SDS and regional regulatory frameworks for handling and labeling requirements.
Monitoring
Typical matrices: fuels and lubricants; ambient and indoor air particulates (after adsorption), surface water and wastewater (primarily in suspended phases), soils and sediments, food-contact materials, and food/feeds in MOSH/MOAH investigations.
Target analyte roles: calibration/QA spikes, retention markers, process controls, and surrogate/internal standards (when isotopically labeled analogues are used).
Analytical control: evaluate recovery, precision, linearity, and detection capability across matrix types; document method performance as part of accreditation requirements.
Health Impact
- Human toxicity: Hexadecane exhibits low acute systemic toxicity but may cause skin irritation (GHS H315). Due to high hydrophobicity, aspiration hazards are managed via safe handling practices. Inhalation exposure is limited by low vapor pressure at room temperature; aerosol/mist exposures should be controlled.
- Occupational exposure: Implement standard chemical hygiene protocols; consult site-specific exposure limits if applicable.
Environmental Impact
- Fate: Very low water solubility and high hydrophobicity favor adsorption to soils/sediments and organic matter. Volatilization from water is limited by low vapor pressure; however, surface films can occur.
- Effects on wildlife: Acute aquatic toxicity is generally low for long-chain alkanes, but physical fouling and chronic exposure to hydrocarbon mixtures can pose risks. Monitor and minimize releases to the environment.
Safety Measures
- Flammability: Combustible liquid (flash point ~136 °C; autoignition ~202 °C). Keep away from heat, hot surfaces, sparks, and open flames.
- Handling: Use in a fume hood or well-ventilated area. Wear appropriate PPE (lab coat, safety glasses, chemical-resistant gloves). Avoid skin contact; wash thoroughly after handling.
- Storage: Tightly closed, in inert-compatible containers, away from ignition sources and oxidizers. Note the melting point (~18 °C); store above this temperature to maintain liquid state or allow controlled warming before use.
Analytical Methods
- Primary techniques: GC-FID for quantification; GC-MS for confirmation and selectivity; GC×GC for complex hydrocarbon mixtures (e.g., MOSH/MOAH profiles).
- Sample preparation: LLE/SPE for water and extracts, solvent dilution for fuels/oils, SPME for headspace screening. Use glassware and solvent blanks to control background hydrocarbons.
- Quality control: Employ calibration with matrix-matched standards when feasible; include procedural blanks, spikes, and duplicates. Use isotopically labeled hexadecane where appropriate to correct for recovery and matrix effects.
