RU58841 Powder 99.9%+ Purity
RU58841 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.
This material is supplied strictly for in vitro research.
It is produced using Anagen Ultra Purification, developed to minimize trace impurities that can interfere with sensitive experimental readouts.
Purity standards. Why 99.9% 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 are strict on purity.
We do not stop at 99.0% or 99.5%.
This material is produced using a more intensive and higher cost purification process, typically achieving purity near 99.9%, 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
Third party verification
- Purity verified by US based independent third party laboratories
- Batch specific lab reports are available on this page under the Lab Reports tab
Stability
Internal stability program data indicates strong stability in solid form and in prepared solutions for at least 24 months at room temperature when stored properly.
Quality control
- Test reports are available under the Lab Reports tab
- Documentation is presented on the product page for review

Fast shipping to Canada, discrete packaging. Good stuff
Not a cheap purchase, and you definitely need the knowledge and equipment to handle it. However, if you’re not satisfied with standard options, this is a strong contender. Anageninc provides excellent support, and their third-party testing gives me confidence in the product’s quality.
Good stuff
Product seems to be effective! International shipping on the first delivery was delayed due to border security (as expected for a mysterious white powder), but every package since, for the last couple years, has arrived in a very prompt and discreet manner! Anagen doesn’t mess around!
