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.
Use a bath-type ultrasonic cleaner at standard cleaning frequency (37–40 kHz). Bath sonication is gentler than a probe sonicator and avoids sample overheating. Sonicate in 5–10 second intervals, checking solubility between pulses, for no more than 2–3 minutes total. Warm the bath to 37 °C if solubility remains poor.
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
