Biological Activity

Potassium thioacetate is a versatile sulfur-introducing reagent and synthetic building block used in the preparation of sulfur-containing organic molecules and bioactive compounds. Serving as a nucleophilic sulfur donor, it enables the functionalization of diverse substrates to generate thiols, thioethers, and sulfur heterocycles. These chemical modifications facilitate the synthesis of specialized enzyme inhibitors, peptidomimetics, and functionalized biomolecules required for probing metabolic and cellular signaling pathways.

Solubility

Batch:
All in vitro solubility values are batch-tested experimental data (non-literature values).
Solvent Solubility & Note
DMSO 22 mg/mL (192.62 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).
