Description

The occurrence of (7R,8R,9S,13S,14S,17S)-7-(9-Bromononyl)-13-methyl-7,8,9,11,12,13,14,15,16,17-decahydro-6H-cyclopenta[a]phenanthrene-3,17-diol 875573-67-4 is closely related to a steroid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(7R,8R,9S,13S,14S,17S)-7-(9-Bromononyl)-13-methyl-7,8,9,11,12,13,14,15,16,17-decahydro-6H-cyclopenta[a]phenanthrene-3,17-diol 875573-67-4 (CAS 875573-67-4), molecular formula C27H41BrO2 and molecular weight 477.52 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C27H41BrO2, (7R,8R,9S,13S,14S,17S)-7-(9-Bromononyl)-13-methyl-7,8,9,11,12,13,14,15,16,17-decahydro-6H-cyclopenta[a]phenanthrene-3,17-diol 875573-67-4 contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 477.52 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
