General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Heptane is an environmentally preferable solvent compared to hexane and thus align with "Safer Solvents and Auxiliaries". Click here for more information.

Application


  • Pt(PPh(3))(4) and Pt(PPh(3))(4)@IL catalyzed hydroboration of ketones.: This study explores the use of n-Heptane as a solvent in the hydroboration of ketones catalyzed by Pt(PPh(3))(4) and Pt(PPh(3))(4)@IL, demonstrating its application in organometallic chemistry and catalytic processes (Krupa et al., 2023).

  • Imidazolium-based ionic liquids as dispersants to improve the stability of asphaltene in Egyptian heavy crude oil.: This research uses n-Heptane in the analysis of asphaltene stability, highlighting its role in petroleum chemistry and the development of more efficient dispersants (Ghanem et al., 2023).

  • A countercurrent chromatography solvent system based on deep eutectic solvents for separation of cis- and trans-crocetin from Gardenia jasminoides Ellis.: This study employs n-Heptane in a novel solvent system for countercurrent chromatography, showcasing its utility in natural product isolation and analytical chemistry (Wen et al., 2023).

  • Volatile Organic Compounds in Disposable Diapers and Baby Wipes in the US: A Survey of Products and Health Risks.: The study includes n-Heptane in the analytical methods to detect volatile organic compounds, emphasizing its importance in environmental health and safety assessments (Lin et al., 2023).

  • Countercurrent chromatography separation of vitamin E isomers in a co-current mode.: This research uses n-Heptane in countercurrent chromatography to separate vitamin E isomers, demonstrating its application in nutritional chemistry and quality control (Hu et al., 2023).
