Ordering Information

Biological Activity

4-Methylsalicylic acid is a benzoic acid derivative that acts as an inhibitor of medium-chain acyl-CoA synthetase. By suppressing medium-chain acyl-CoA synthetase activity, it interferes with the activation and subsequent metabolic processing of medium-chain fatty acids and xenobiotic carboxylic acids within fatty acid oxidation pathways. This inhibition modulates cellular acyl-CoA homeostasis and lipid metabolic fluxes in hepatic energy pathways. [1]

All in vitro solubility values are batch-tested experimental data (non-literature values).
Solvent Solubility & Note
DMSO 30 mg/mL (197.17 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.)
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).
