2-Methylhexanoic acid
Based on 1 Customer Validation
2-Methylhexanoic acid is a saturated branched-chain carboxylic acid with a strong "fatty" or "oily" odor. At high concentrations, it is often described as having the smell of lard, chicken fat or sweat; when diluted, it exhibits a dairy, cream or cheese aroma. Therefore, it is commonly used in the formulation of milk, meat (pork/chicken) and baked food flavors. 2-Methylhexanoic acid occurs naturally in fresh apples, cheese, grape brandy, lamb, potatoes and tea.

Biological Activity
2-Methylhexanoic acid does not exhibit genotoxicity or cytotoxicity in human cells in the BlueScreen assay, with and without metabolic activation[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
2-Methylhexanoic acid (10-250 mg/kg/day; p.o., gavage; daily; male: 42 days; female: 41-53 days) (via read-across to 2-ethylbutyric acid) has a repeated dose NOAEL of 10 mg/kg/day for males, 50 mg/kg/day for females; a fertility NOAEL of 250 mg/kg/day; and a developmental toxicity NOAEL of 50 mg/kg/day in Sprague Dawley rats[1].
2-Methylhexanoic acid (300 mg/kg/day; dietary; daily; 90 days) (via read-across to 2-ethylbutyric acid) has a 90-day repeated dose NOAEL of 300 mg/kg/day in male Sprague Dawley rats[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (19.20 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (19.20 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
