n-Heptane GC

n-Heptane GC grade CAS: 142-82-5 | MF: CH3(CH2)5CH3 | MW: 100.21, Buy now for reliable and Reproducible results from Bluster GC Solvent at Chemical World.

n-Heptane GC (CAS No. 142-82-5) is a clear colorless liquid with a faint petroleum-like smell as is characteristic of straight-chain alkanes. IIt has the molecular formula C₇H₁₆ and is also known by alternative names such as Heptan, Dipropylmethane, Heptyl hydride, Dipropyl methane, Skellysolve C, Gettysolve-C, and n-Heptan. In comparison to the technical-grade heptane, n-Heptane GC only comprises the straight-chain isomer and is not mixed with other heptane isomers. It is not soluble in water and is extensively used in research laboratories and in analytical laboratories. The GC-grade classification assures that the solvent has been subjected to a vigorous purification process that ensures it satisfies the stringent standards required of a gas chromatography and analytical analysis.

Applications

  • n-Heptane GC has a wide application in the chemical research and analysis laboratories, because it is non-polar, and it is highly purified.
  • n-Heptane GC is the typical non-polar solvent used in the process of organic synthesis and extraction, especially in cases when hydrophobic compounds have to be dissolved effectively.
  • This is a common reference solvent or calibration standard in gas chromatography to measure retention indices and assure proper chromatography.

Key Characteristics

  • High Purity: Made to GC-grade standards thus with minimal interference and the best analytical results.
  • Negligible Impurities: There are insignificantly low levels of impurities, which minimize the chance of contamination and increase the reproducibility.
  • Low Water Content and UV Absorbance: Suitable with sensitive analysis protocols that need clean baselines.Analytical Flexibility: It is applicable when it comes to GC analysis, organic synthesis and extraction.

Overview

The n-Heptane GC Grade (CAS No. 142-82-5) is a very pure, non-polar solvent that has been used in gas chromatography and other sophisticated methods of analysis. With a molecular formula of C₇H₁₆, it delivers excellent chromatographic performance due to its low UV absorbance, minimal water content, and absence of isomeric impurities. n-Heptane GC is widely used for retention index calibration, solvent-based analyses, and controlled organic synthesis.

The n-Heptane GC Grade that is to be purchased by the laboratories is available in credible chemical suppliers like Chemical World to serve the purposes of analysis, pharmaceutical, and research centers in the USA. Pricing of n-Heptane GC Grade is determined by the size of the packaging, purity certification, and quantity of order, with competitive pricing being offered for both one-time laboratory and large order needs. The sourcing is Chemical World, which guarantees reliability, documentation, and uniform supply to achieve analytical excellence.
