Biological Activity

trans-2-Methyl-2-pentenoic Acid is an unsaturated short-chain fatty acid derivative and volatile aroma compound primarily utilized as a food flavoring agent. It contributes to sweet, berry-like odor profiles and sensory attributes in food matrixes. As an aliphatic carboxylic acid, it influences olfactory perception pathways by interacting with odorant receptors to mediate characteristic sweet and fruity flavor notes. [1]

Solvent Solubility & Note
FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
