rel-(1aR,2aS,5aS,5bS)-Hexahydro-4H-oxireno[2',3':3,4]cyclopenta[1,2-b]furan-4-one (CAS 26115-01-5), molecular formula C7H8O3 and molecular weight 140.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of rel-(1aR,2aS,5aS,5bS)-Hexahydro-4H-oxireno[2',3':3,4]cyclopenta[1,2-b]furan-4-one (C7H8O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), rel-(1aR,2aS,5aS,5bS)-Hexahydro-4H-oxireno[2',3':3,4]cyclopenta[1,2-b]furan-4-one 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.
