2-((8S,9R,10S,13R,14S,16R,17R)-9-Fluoro-17-hydroxy-13-(iodomethyl)-10,16-dimethyl-3,11-dioxo-6,7,8,9,10,11,12,13,14,15,16,17-dodecahydro-3H-cyclopenta[a]phenanthren-17-yl)-2-oxoethyl acetate CAS 1881-17-0 chemical structure

Description

2-((8S,9R,10S,13R,14S,16R,17R)-9-Fluoro-17-hydroxy-13-(iodomethyl)-10,16-dimethyl-3,11-dioxo-6,7,8,9,10,11,12,13,14,15,16,17-dodecahydro-3H-cyclopenta[a]phenanthren-17-yl)-2-oxoethyl acetate (C24H28FIO6) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine/iodine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 2-((8S,9R,10S,13R,14S,16R,17R)-9-Fluoro-17-hydroxy-13-(iodomethyl)-10,16-dimethyl-3,11-dioxo-6,7,8,9,10,11,12,13,14,15,16,17-dodecahydro-3H-cyclopenta[a]phenanthren-17-yl)-2-oxoethyl acetate (CAS 1881-17-0), a certified reference material (molecular formula C24H28FIO6, MW 558.38 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2-((8S,9R,10S,13R,14S,16R,17R)-9-Fluoro-17-hydroxy-13-(iodomethyl)-10,16-dimethyl-3,11-dioxo-6,7,8,9,10,11,12,13,14,15,16,17-dodecahydro-3H-cyclopenta[a]phenanthren-17-yl)-2-oxoethyl acetate 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.
