(13s,14s,17s)-13-ethyl-3-methoxy-7,11,12,13,14,15,16,17-octahydro-6h-cyclopenta[a]phenanthren-17-ol(non-preferred name) 7790-39-8 KST-1A8207 (CAS 7790-39-8), molecular formula I2Pt and molecular weight 448.89 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (13s,14s,17s)-13-ethyl-3-methoxy-7,11,12,13,14,15,16,17-octahydro-6h-cyclopenta[a]phenanthren-17-ol(non-preferred name) 7790-39-8 KST-1A8207 (I2Pt) is characterized by iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (13s,14s,17s)-13-ethyl-3-methoxy-7,11,12,13,14,15,16,17-octahydro-6h-cyclopenta[a]phenanthren-17-ol(non-preferred name) 7790-39-8 KST-1A8207 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
