CATO supplies (3aR,4R,5R,6aS)-Hexahydro-5-hydroxy-4-[(1E,3S)-3-hydroxy-1-octen-1-yl]-2H-cyclopenta[b]furan-2-one (CAS 26054-67-1), a certified reference material (molecular formula C15H24O4, MW 268.35 g/mol) for analytical method development and quality control.
(3aR,4R,5R,6aS)-Hexahydro-5-hydroxy-4-[(1E,3S)-3-hydroxy-1-octen-1-yl]-2H-cyclopenta[b]furan-2-one (C15H24O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
