Product Description
2-Pentylfuran is a compound extracted from the steam volatile oil obtained from potatoes at normal pressure.
2-Pentylfuran (2-Amylfuran) (CAS#: 3777-69-3) is a volatile organic compound commonly found in various food products, such as coffee, bread, and roasted nuts. It has a molecular formula of C9H14O and a molecular weight of 138.21. 2-Pentylfuran is a naturally occurring flavoring ingredient and may be a biomarker for lung colonization/infection by fungal pathogens. It is also responsible for the undesirable reversion flavor of soybean oil.
Biological Activity I Assay Protocols (From Reference)
Targets
2-Pentylfuran does not have a specific biological target but functions as a volatile flavor compound and potential biomarker. As a furan derivative, it may interact with biological membranes and olfactory receptors. Its role as a biomarker for fungal infection suggests that it may be produced by fungal metabolism and detected in breath or other biological samples.
ln Vitro
In vitro, 2-Pentylfuran is used as a reference standard and in studies of food flavor and volatile organic compounds. Its activity is related to its role as a flavoring ingredient rather than a pharmacologically active compound. It is a valuable tool for studying the chemistry of food flavors and for developing analytical methods for volatile organic compounds.
ln Vivo
In vivo, 2-Pentylfuran is not used as a therapeutic agent but may be a biomarker for fungal lung infections. Its detection in breath samples may indicate the presence of fungal pathogens.
Enzyme Assay
The in vitro assays for 2-Pentylfuran typically involve analytical chemistry methods such as GC-MS or GC-FID for quantification in food and biological samples. The compound is extracted from samples using headspace or solid-phase microextraction and analyzed by GC-MS.
Cell Assay
For in vitro cellular assays, 2-Pentylfuran is not typically used as a pharmacologically active compound. It may be used in studies of fungal metabolism, where fungal cultures are analyzed for 2-pentylfuran production.
Animal Protocol
For in vivo studies, 2-Pentylfuran is not administered to animals as a therapeutic agent. It may be measured in breath or blood samples from patients with fungal infections.
ADME/Pharmacokinetics
The pharmacokinetic properties of 2-Pentylfuran are not relevant, as it is a volatile flavor compound rather than a therapeutic agent. The compound has a molecular weight of 138.21. It is rapidly volatilized and eliminated.
Toxicity/Toxicokinetics
Toxicology data for 2-Pentylfuran are limited. At the concentrations found in food, it is generally recognized as safe.

Additional Infomation
2-Pentylfuran is a type of furan compound characterized by the substitution of an pentyl group for a hydrogen atom at the 2-position of the furan molecule. It is found in many heat-processed foods and beverages. 2-Pentylfuran can be used as a metabolite of Aspergillus, a metabolite in human urine, a volatile oil component, an insect repellent, a flavoring agent, a plant growth stimulant, and a bacterial metabolite. It has been reported to be found in Magnolia officinalis, Daphne odora, and several other organisms with relevant data. 2-Pentylfuran is a metabolite of or produced by Saccharomyces cerevisiae.

Solubility Data
Solubility (In Vitro)
DMSO : ~100 mg/mL (~723.54 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (18.09 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.5 mg/mL (18.09 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
