Estra-4,9-diene-3,17-dione is a potent synthetic steroid intermediate defined by its conjugated diene system. Synthesized via aromatization or dehydration of estrone derivatives, it serves as a critical precursor for high-potency androgens and estrogens. Molecular Formula: C18H20O2; CAS No.: 53-43-4.
Strictly controlled substance; requires storage in cool, dry environments away from oxidizers. Handling mandates PPE including respirators and chemical-resistant gloves due to endocrine disruption risks. Clinical use is limited to regulated industrial synthesis only.
