Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
It is not recommended to store DMSO stock solutions at room temperature. Once the stock solution is prepared, aliquot into single-use volumes and store at −20 °C (or −80 °C for sensitive compounds). Room-temperature storage accelerates chemical degradation and moisture uptake. When ready to use, thaw an aliquot at room temperature, use immediately, and avoid repeated freeze-thaw cycles.
Sonication time depends on compound solubility and concentration. In most cases, 1–3 minutes of intermittent bath sonication is sufficient to dissolve small molecule compounds in DMSO. For poorly soluble compounds, warming the solvent to 37–50 °C combined with brief vortexing between sonication pulses can improve dissolution. If the compound remains undissolved, prepare a more dilute stock solution.
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
