RU58841 Solution 30mL 99.9%+ purity
RU58841 Solution also referenced as RU-58841 is a nonsteroidal androgen receptor antagonist.
It has been studied in vitro as a research compound in androgen receptor signaling work, including models relevant to androgen responsive skin and hair follicle biology.
RU58841 is produced using Anagen Ultra Purification, typically achieving purity near 99.9% as confirmed by batch specific third party lab reports.
Purity standards. Why solution purity still matters
The general market standard for research chemicals is 98% or 99.0% purity.
That can be acceptable for certain exploratory work, but for sensitive in vitro workflows even small residual byproducts can introduce variability.
At Anageninc, we take purity further.
We do not stop at 99.0% or 99.5%.
This RU58841 solution is prepared using a more intensive and higher cost purification approach to support a high purity specification, reducing trace impurities that can impact analytical interpretation and experimental reproducibility.
- Lower background noise when trace peaks matter
- Cleaner baselines for chromatography based verification workflows
- Improved reproducibility across repeats when impurities are a confounder
Solution grade quality control
For solutions, purity is only part of the quality equation.
Concentration accuracy matters for reproducible work.
Each batch is tested to confirm the solution concentration is within 10% of the labeled specification.
Concentration options: 5% (50mg/mL) or 8% (80mg/mL).
Select concentration and solvent from the dropdown menu on this page.
- Purity verified by US based independent third party laboratories (see Lab Reports tab)
- Concentration verified within 10% of the labeled specification
- Content: 30 mL (slightly overfilled)
Solvent options

FAQ
How stable is RU58841?
RU58841 is stable for extended periods. Claims about rapid instability are not universally verifiable across reproducible lab assays.
In our internal R&D, we performed HPLC stability testing under multiple conditions, including room temperature testing and accelerated stability testing at elevated temperatures in the 30 to 40 C range.
HPLC results showed the RU58841 powder exhibited less than 1% degradation after approximately 2.5 to 3 years.
For the pre mixed RU58841 solution, HPLC results over the same timeframe showed the measured concentration remained within 10% of the label claim, meeting our acceptance criteria.
This is why we guarantee stability for at least 24 months at room temperature.
Which solvent is used for the RU58841 solution?
RU58841 solution is offered in two solvent options. Select your preferred solvent from the dropdown menu on this page.
