(1R,4S)-3-(methoxycarbonyl)bicyclo[2.2.1]Hepta-2,5-diene-2-carboxylic acid (CAS 121701-12-0), molecular formula C10H10O4 and molecular weight 194.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1R,4S)-3-(methoxycarbonyl)bicyclo[2.2.1]Hepta-2,5-diene-2-carboxylic acid (C10H10O4) 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 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.
