Overview
Nonadecane is a straight-chain alkane with 19 carbon atoms, classified as a high-purity standard in analytical chemistry. It is widely recognized for its role in gas chromatography (GC) as a retention index marker due to its predictable elution behavior. As a non-polar compound, it serves as a reference for calibrating instruments and testing column performance. Industrially, nonadecane is synthesized via petroleum refining or Fischer-Tropsch processes. Its inert nature and stability make it suitable for research applications, particularly in hydrocarbon studies and phase behavior experiments.
Physical and Chemical Properties
Nonadecane exhibits typical alkane characteristics: low reactivity, hydrophobicity, and a waxy solid or liquid state at room temperature, depending on temperature variations. Its melting point (32–34°C) and boiling point (330°C) reflect its long hydrocarbon chain. The density (0.785 g/cm³) is lower than water, consistent with aliphatic hydrocarbons. Chemically, it resists oxidation under standard conditions but combusts in air to form carbon dioxide and water. Its solubility profile favors organic solvents like hexane or toluene, while remaining insoluble in polar solvents such as water or ethanol.
Main Applications
In chromatography, nonadecane is a critical standard for establishing retention indices, ensuring accurate compound identification in GC analyses. Laboratories use it to validate column efficiency and instrument calibration. Beyond analytics, it functions as a solvent in specialty formulations and a raw material for synthesizing surfactants or lubricant additives. Its thermal stability also makes it a candidate for phase-change materials (PCMs) in thermal energy storage systems.
Safety and Storage
Nonadecane poses moderate hazards: it is combustible and may cause mild skin or eye irritation upon contact. Proper storage requires airtight containers in cool, ventilated areas, away from open flames or sparks. Spills should be contained with inert absorbents. Personal protective equipment (PPE) like gloves and goggles is recommended during handling. Safety Data Sheets (SDS) must be reviewed prior to use, emphasizing fire prevention and first-aid measures for accidental exposure.
B2B Procurement Guide
When sourcing nonadecane, prioritize suppliers offering certified purity levels (e.g., ≥98% for analytical standards). Request batch-specific COAs to confirm identity, assay, and impurity profiles. Bulk purchases (kilograms or larger) may reduce costs but require verification of storage stability. For international procurement, ensure compliance with regional regulations (e.g., REACH in the EU). Reliable suppliers often provide technical support and logistics tailored to chemical handling requirements.
