Overview
Chemical & Pharmacological Profile: OTR-AC
OTR-AC (also designated as Ostarine O-Acetate or MK-2866 Acetate) is a modified esterified derivative of the classical selective androgen receptor modulator Enobosarm. The addition of the ester chain enhances the molecule’s lipophilicity, improving biological absorption and extending its effective plasma half-life relative to free-base Ostarine.
Chemical Identification
- IUPAC Name: (2S)-3-(4-cyanophenoxy)-N-[4-cyano-3-(trifluoromethyl)phenyl]-2-hydroxy-2-methylpropanamide acetate ester
- CAS Number: 841205-47-8
- Chemical Formula: C21H16F3N3O4
- Purity Grade: ≥99.0% (Reversed-Phase HPLC Certified)

- Solubility: Soluble in DMSO, Ethanol, and PEG-400
- Storage: Store at 2–8°C in an airtight container with desiccant. Protect from humidity and heat.
Research Context
OTR-AC binds selectively to the androgen receptor in skeletal muscle and bone tissue without cross-reacting with progesterone or estrogen receptors. It is investigated for lean mass preservation, osteogenic density, and athletic recovery research.
