4-(1,3,3-Trimethyl-7-oxabicyclo[4.1.0]hept-2-yl)-3-buten-2-one (CAS 190059-33-7), molecular formula C13H20O2 and molecular weight 208.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(1,3,3-Trimethyl-7-oxabicyclo[4.1.0]hept-2-yl)-3-buten-2-one (C13H20O2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-(1,3,3-Trimethyl-7-oxabicyclo[4.1.0]hept-2-yl)-3-buten-2-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.
