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.
When solubility is listed as < 1 mg/mL, the compound dissolves to less than 1 mg per milliliter in water at 25 °C, pH 7.4. Such compounds require an organic co-solvent such as DMSO to prepare a concentrated stock, which is then diluted into aqueous assay buffer. For cell-based assays, keep the final DMSO concentration below 0.1% (v/v) to avoid solvent-induced cytotoxicity.
Try the following steps: (1) warm the DMSO solvent to 37–50 °C before adding the compound; (2) vortex vigorously for 30 seconds then bath-sonicate for 1–2 minutes; (3) if still undissolved, prepare a more dilute stock. Note that maximum solubility values are reference conditions — actual solubility can vary with temperature, solvent lot, and compound batch. Contact BioHippo support if dissolution problems persist.
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
