Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

2-[(8R,9S,10R,13S,14S,15R,17S)-10,13-dimethyl-17-oxidanyl-3-oxidanylidene-1,2,6,7,8,9,11,12,14,15,16,17-dodecahydrocyclopenta[a]phenanthren-15-yl]ethanoic acid 2-[(8R,9S,10R,13S,14S,15R,17S)-17-hydroxy-10,13-dimethyl-3-oxo-1,2,6,7,8,9,11,12,14,15,16,17-dodecahydrocyclopenta[a]phenanthren-15-yl]acetic acid 678-65-9 A835910 (CAS 678-65-9) is a high-purity analytical reference standard with the molecular formula C8H6F8 and a molecular weight of 254.12 g/mol.

Structurally, 2-[(8R,9S,10R,13S,14S,15R,17S)-10,13-dimethyl-17-oxidanyl-3-oxidanylidene-1,2,6,7,8,9,11,12,14,15,16,17-dodecahydrocyclopenta[a]phenanthren-15-yl]ethanoic acid 2-[(8R,9S,10R,13S,14S,15R,17S)-17-hydroxy-10,13-dimethyl-3-oxo-1,2,6,7,8,9,11,12,14,15,16,17-dodecahydrocyclopenta[a]phenanthren-15-yl]acetic acid 678-65-9 A835910 (C8H6F8) contains fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 254.12 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
