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
This product is offered in two solvent options.
Select your preferred solvent from the dropdown menu on this page.
- Ethanol + Propylene Glycol
- K&B Solution Solvent
Stability
Internal stability program data indicates strong stability in prepared solutions for at least 24 months at room temperature when stored properly.
For best stability, store tightly sealed and protected from light and direct sunlight.
Quality control
- Test reports are available under the Lab Reports tab
