Heptane, which is HPLC Grade (CAS: 142-82-5), is a linear alkane, used in laboratory practice as a non-polar solvent in High-Performance Liquid Chromatography (HPLC) applications. It has a chemical formula, CH3(CH2)5CH3. This substance is otherwise known as n-heptane, dipropylmethane, heptan, heptyl hydride and dipropyl methane. Heptane is a non-polar type of molecule, hence, it cannot be easily dissolved in polar solvents such as water, but can readily be dissolved in other organic non-polar solvents.

Applications

  • Heptane HPLC Grade is a more environmental friendly alternative to Hexane in HPLC.
  • It may be used to prepare the solvent mixes of the purification of fatty acid methyl ester derivatives of N-acylpyrrolidines (FAMEs) using TLC.

Key Characteristics

  • High Purity: Guaranteed that it has few impurities to enhance the quality of the result of HPLC.
  • Low UV Absorbance: It is appropriate in UV-sensitive applications and the baseline noise is low and the detection is adequate.
  • Low Water Content: Reduces the chances of undesirable hydrolysis reactions and foundation effects in HPLC analysis.
  • Reproducibility: Produces reproducible as well as consistent results which is important in science research as well as in industry.

Overview

Heptane HPLC Grade (CAS: 142-82-5), also known as n-heptane, dipropylmethane, heptan, heptyl hydride, or dipropyl methane, is a linear-chain alkane, the formula of which is CH3(CH2)5CH3. It is colorless, and chemically stable, and non-polar and can therefore be used in many chromatographic techniques especially High-Performance Liquid Chromatography (HPLC).

Frequently Asked Questions

1. What are the primary applications of Heptane HPLC?
Heptane HPLC is a hydrocarbon solvent intended for compatible chromatographic and analytical laboratory procedures. It can be useful in non-polar solvent systems, sample preparation, and method development involving suitable organic compounds.
2. How does heptane function in normal-phase chromatography?
Heptane can serve as a non-polar mobile-phase component in appropriate normal-phase separations. Its proportion in the solvent mixture can influence analyte retention and elution, depending on the stationary phase and compounds being analyzed.
3. What is the molecular formula of heptane?
Heptane has the molecular formula C7H16 and a molecular weight of approximately 100.20 g/mol. The name heptane can refer to the straight-chain compound or, in broader usage, to a family of structural isomers.
4. Why might a laboratory choose heptane for non-polar compounds?
Heptane is a non-polar hydrocarbon capable of dissolving many hydrophobic substances. It can be useful when polar solvents would be unsuitable for the sample or would not provide the desired separation behavior.
5. Can Heptane HPLC be combined with other solvents?
Yes, heptane can be incorporated into compatible solvent mixtures to adjust solvent strength and selectivity. Before combining solvents, analysts should confirm miscibility, material compatibility, and the requirements of their procedure.
6. What advantage does a suitable HPLC-grade heptane provide?
An appropriate analytical grade helps limit impurities that could interfere with separation or detection. Controlled solvent quality supports more consistent chromatographic conditions and reduces the likelihood of solvent-related background interference.
7. How does heptane differ from pentane?
Both are non-polar alkanes, but heptane contains seven carbon atoms, whereas pentane contains five. This structural difference affects their boiling points, volatility, and other physical properties.
8. What handling precautions apply to Heptane HPLC?
Heptane is flammable, and its vapors should be controlled during use. Keep it away from ignition sources, use suitable ventilation, and follow the product SDS for personal protection and storage requirements.
9. Which technical records should be reviewed before using Heptane HPLC?
Consult the product's available specification and COA for quality information, together with the SDS for safe handling and storage guidance. Confirm the exact grade and applicable requirements before using the solvent in a validated method.
10. How can US laboratories order Heptane HPLC from Chemical World?
Customers can purchase Heptane HPLC through Chemical World. The sales team can provide information about current availability, pricing, and bulk quantities.
