Task: Please create a description for a molecule.
Molecule SMILES: C[C@]12CC[C@@H]3c4ccc(OC(=O)N(CCCl)CCCl)cc4CC[C@H]3[C@@H]1CC[C@@H]2OP(=O)(O)O
Constraint: Answer the question with complete sentences.
Result: The molecule is a steroid phosphate which is the 17-O-phospho derivative of estramustine. It is a steroid phosphate, a carbamate ester and an organochlorine compound. It derives from an estramustine. It is a conjugate acid of an estramustine phosphate(2-).
