CATO supplies (Z)-7-((1R,2R,5S)-5-Hydroxy-2-((S,1E,5Z)-3-hydroxyocta-1,5-dien-1-yl)-3-oxocyclopentyl)hept-5-enoic acid (CAS 71902-47-1), a certified reference material (molecular formula C20H30O5, MW 350.45 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H30O5, (Z)-7-((1R,2R,5S)-5-Hydroxy-2-((S,1E,5Z)-3-hydroxyocta-1,5-dien-1-yl)-3-oxocyclopentyl)hept-5-enoic acid contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 350.45 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).
As a certified reference material (CRM), (Z)-7-((1R,2R,5S)-5-Hydroxy-2-((S,1E,5Z)-3-hydroxyocta-1,5-dien-1-yl)-3-oxocyclopentyl)hept-5-enoic acid 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.
