Safety

For Research Use Only. Not for use in diagnostic or therapeutic procedures, and not for human or veterinary use. Handle in accordance with the Safety Data Sheet and your institution's chemical hygiene plan.

In Vitro

SolventSolubilityNotes
DMSO125 mg/mL (855.64 mM)requires sonication; use freshly opened DMSO (absorbed moisture lowers solubility)

Aliquot the stock solution and store it at -80°C (up to 6 months) or -20°C (up to 1 month); avoid repeated freeze-thaw cycles.

In Vivo

Choose the formulation that suits the animal model and route of administration; percentages are volume ratios of the final working solution. Start from a clear DMSO stock (see In Vitro above), add the co-solvents one at a time in the order listed, mixing after each addition, and prepare the working solution fresh on the day of dosing. If precipitation or phase separation occurs, gentle warming or sonication can help.

Protocol 1

Composition10% DMSO + 40% PEG300 + 5% Tween-80 + 45% saline
Result≥ 2.08 mg/mL (14.24 mM); clear solution
How to prepareGives a clear solution at ≥ 2.08 mg/mL (saturation not determined). For 1 mL of working solution: add 100 μL DMSO stock (20.8 mg/mL) to 400 μL PEG300; then 50 μL Tween-80; then 450 μL saline to bring the volume to 1 mL. Saline: dissolve 0.9 g sodium chloride in ddH2O and make up to 100 mL.

Protocol 2

Composition10% DMSO + 90% (20% SBE-β-CD in saline)
Result≥ 2.08 mg/mL (14.24 mM); clear solution
How to prepareGives a clear solution at ≥ 2.08 mg/mL (saturation not determined). For 1 mL of working solution: add 100 μL DMSO stock (20.8 mg/mL) to 900 μL 20% SBE-β-CD in saline. 20% SBE-β-CD in saline: dissolve 2 g SBE-β-CD powder in 10 mL saline until clear (4°C, store up to one week).

Need this compound in a format that drops straight into your assay? We can tailor formulation, chemistry, and documentation so your results stay consistent across runs and re-orders.

  • Format options: solid or pre-dissolved solution (choose solvent), target concentration, aliquots, light/moisture-protected packaging
  • Chemistry options: free base/acid vs salt forms, hydrate/solvate preference, stereoisomer control (single enantiomer or racemate), close analogs
  • Add-on labels & handles: D/¹³C/¹⁵N isotopes (LC-MS/internal standards), azide/alkyne or other functional handles for conjugation
  • QC & documentation: standard COA or enhanced analytical pack (HPLC/LC-MS/NMR), chiral purity, residual solvents, water content (KF), method-specific specs
  • Scale & continuity: mg to gram scale, bulk pricing, lot reservation, repeat-order continuity

To quote quickly, tell us: compound name + CAS/structure (SMILES or mol file), intended assay context, solvent preference, salt/stereochemistry requirements, purity/QC level, and the amount (mg–g).
