Description

(+)-cucurbic acid (3R,6S,7S)-cucurbic acid 58240-50-9 CHEBI:18446 {(1R,2S,3S)-3-hydroxy-2-[(2Z)-pent-2-en-1-yl]cyclopentyl}acetic acid (CAS 58240-50-9), molecular formula C12H20O3 and molecular weight 212.29 g/mol, is a CATO reference standard with documented purity and traceability.

(+)-cucurbic acid (3R,6S,7S)-cucurbic acid 58240-50-9 CHEBI:18446 {(1R,2S,3S)-3-hydroxy-2-[(2Z)-pent-2-en-1-yl]cyclopentyl}acetic acid (C12H20O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 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.

As a certified reference material (CRM), (+)-cucurbic acid (3R,6S,7S)-cucurbic acid 58240-50-9 CHEBI:18446 {(1R,2S,3S)-3-hydroxy-2-[(2Z)-pent-2-en-1-yl]cyclopentyl}acetic 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.
