Basic Information

Product Name: N-PENTADECANE; Alias: Pentadecane, n-Pentadecane, Alkane C15, Normal Pentadecane

CAS Number: 629-62-9

Molecular Formula: C??H??

Molecular Weight: 212.41 g/mol

Structural Formula: CH?(CH?)??CH? (a straight-chain saturated alkane with high chemical stability and typical alkane inertness)

Classification: Aliphatic hydrocarbon, straight-chain alkane, organic solvent, chromatographic standard substance, organic intermediate, research reagent, industrial additive

Physical & Chemical Properties

N-Pentadecane is a colorless, transparent liquid at room temperature, with a mild hydrocarbon odor. It is insoluble in water and methanol, slightly soluble in ethanol, and miscible with most organic solvents. It is stable under normal temperature and pressure, with strong chemical inertness, but sensitive to high temperature and strong oxidants, and may decompose or react violently under extreme conditions. Its density is 0.769 g/cm3 (25°C), boiling point is 270°C, melting point is 8-10°C, flash point (closed) is 132.2°C, refractive index (n20/D) is 1.431. It is non-hygroscopic, flammable, and needs to be stored properly to avoid volatilization and contamination.

Key physical and chemical parameters are detailed in the specification table below, meeting the requirements of industrial grade, reagent grade, research grade and chromatographic standard grade.

Main Uses

N-Pentadecane is an important straight-chain alkane, widely used in chemical analysis, organic synthesis, industrial production and other fields, mainly used as follows:

Chromatographic Analysis Standard: Used for calibrating chromatographic instruments, verifying analytical methods and quantifying unknown samples, suitable as an internal standard substance for gas chromatography.
Organic Solvent: Used as a non-polar solvent for dissolving non-polar compounds, and as a diluent for coatings, inks and adhesives.
Organic Synthesis Intermediate: Used as a raw material for synthesizing higher alkanes, fatty acids, surfactants, synthetic lubricants and fuel additives.
Industrial Additives: Used as a lubricant additive, plasticizer, softener, and component of paraffin and wax products to adjust product performance.
Research & Laboratory Application: Used as a research reagent in organic chemistry, analytical chemistry and other experiments, suitable for laboratory research and small-batch production.
Other Fields: An important component of tobacco flavor, and used as a reference substance in petroleum fractionation and a heat transfer medium in low-temperature experiments.

Packaging & Storage

Packaging Method

Lab/Research Grade & Chromatographic Standard Grade: 10mL-1L sealed glass or HDPE plastic bottles, suitable for laboratory use and chromatographic analysis.

Industrial Grade: 25kg plastic barrels, 200kg galvanized iron drums or IBC containers; customized packaging available for industrial batch supply.

Storage Method

Store in a cool, dry, well-ventilated warehouse at 0-30°C, keep containers tightly sealed to prevent volatilization and leakage. Avoid contact with strong oxidants, fire and heat sources, and store separately from food and edible additives. Shelf life is 24 months under standard storage conditions; use opened products within 6 weeks and seal containers in time after use.
