What Is Altrenogest?
Altrenogest Powder is a synthetic progestogen derived from 19-nortestosterone, structurally related to trenbolone, with an allyl group at the 17α position. Our pharmaceutical-grade Altrenogest is a white to off-white powder with assay consistently above 98% by HPLC.
Manufactured via stereoselective multi-step steroid synthesis and refined by multi-stage HPLC purification under GMP-aligned process control, our Altrenogest API features tightly controlled impurity profiles, robust chemical stability at 2–8°C, and reliable batch-to-batch reproducibility. It is freely soluble in chloroform, soluble in acetone, sparingly soluble in ethanol, and practically insoluble in water.
What Are the Official Quality Test Results?
Every batch undergoes full analytical testing in HDM BIO's in-house QC laboratory, with a batch-specific COA issued for every order.

What Is Altrenogest Used For?
Altrenogest API is a veterinary steroid hormone raw material used across pharmaceutical research and formulation development:
- Oral veterinary dosage form development: Raw material for developing oral solutions and liquid formulations for swine and equine applications, subject to applicable pharmacopeial and regulatory requirements.
- Estrus synchronization research: Estrous cycle control and synchronization formulation development in sow and mare research models.
- Reproductive physiology research: Progestogen receptor signaling and ovarian function mechanism experiments in veterinary species.
- Reference standard development: Pharmacopeial reference material for analytical method validation and quality control.

FAQ
Q: What is Altrenogest?
A: Altrenogest is a synthetic progestogen derived from 19-nortestosterone, with an allyl group at the 17α position. It is a veterinary steroid hormone API used in swine and equine reproductive management research.
Q: What is the CAS number?
A: CAS 850-52-2. Molecular formula C₂₁H₂₆O₂; molecular weight 310.44 g/mol.
Q: What is Altrenogest used for?
A: Altrenogest API is used as a raw material for veterinary oral solution development, estrus synchronization research in sows and mares, reproductive physiology studies, and as an analytical reference standard. It is a research-grade veterinary API intermediate.
Q: What is the difference between Altrenogest and human progestogens?
A: Altrenogest is a 19-nortestosterone derivative developed specifically for veterinary reproductive management in swine and equine species. Human progestogens such as MPA and megestrol acetate are formulated for human indications; Altrenogest is not for human use.
