About 17β-Hydroxyprogesterone
17β-Hydroxyprogesterone is supplied as an analytical reference standard. It is registered under CAS number 604-09-1.
The compound is characterised by its molecular formula C21H30O3 and a molecular weight of 330.46, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 330.2195 Da, a calculated LogP of 3.84, a topological polar surface area of 54.37 Ų. It presents 1 hydrogen-bond donor and 3 acceptors. The structure carries 6 defined stereocentres, which is relevant wherever a stereochemically defined standard is required. These values are commonly used to anticipate chromatographic retention and to plan ionisation conditions during method development.
Each pack ships with a certificate of analysis reporting purity of 95%+ together with the supporting analytical data — HNMR, MS and HPLC or GC traces — so the material can be released straight into your own QC workflow. Recommended storage: -20℃±5℃.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
