What Is RU58841? A Research Compound Overview
RU58841 is a non-steroidal androgen receptor antagonist widely referenced in follicle-biology and androgen-signaling research. It is studied as a topical research agent in model systems. This overview covers what RU58841 is, what researchers study it for, and how to verify research-grade material.

Research background
RU58841 was developed as a non-steroidal compound that binds the androgen receptor and blocks androgen-driven signaling locally in model systems. Because androgen signaling is central to follicle-biology research, RU58841 is used as a reference antagonist in topical and cell-culture studies where researchers want local AR blockade without systemic exposure in their model.
What RU58841 is studied for
In laboratory research (cell-culture and non-clinical model systems), RU58841 is studied for its role in:
- Androgen receptor antagonism — competitive AR binding in reporter and cell-culture assays.
- Follicle-biology research — androgen-driven signaling in follicle model systems.
- Topical-delivery research — local activity in dermal model systems.
All of this is laboratory research; RU58841 offered here is a research chemical only, supplied for in-vitro and non-clinical study.
How research-grade RU58841 is verified
Every batch that ships from a credible US supplier should arrive with a third-party Certificate of Analysis (COA) for that exact lot. Peptide Technologies publishes a COA on every batch and ties it to a QR code on the vial. A complete COA reports:
- Identity — mass spectrometry (ESI-MS) confirming the observed mass matches the theoretical mass of the target compound.
- Purity — reverse-phase HPLC, reported as percent peak area (typically at 220 nm). Research-grade material is ≥98–99% by area.
- Net content — gravimetric confirmation the vial holds the stated mass within tolerance.
- Endotoxin — LAL assay below research thresholds, where applicable.
If a vendor cannot show you a lot-specific COA, you cannot verify what is in the vial. Browse the public COA library →
How to source research-grade material
For laboratory research, sourcing quality comes down to a few checks:
- Lot-specific COA from an accredited, independent laboratory — not a generic marketing PDF.
- HPLC purity ≥98% by peak area, with the chromatogram shown.
- US synthesis and finishing, so the chain of custody is documented end to end.
- Cold-chain shipping for lyophilized material, so the product arrives stable.
