(1S,4S,6R)-5-(tert-butoxycarbonyl)-7-(trifluoromethyl)-2-oxa-5-azabicyclo[4.1.0]Heptane-4-carboxylic acid (CAS 1955485-23-0) is a high-purity analytical reference standard with the molecular formula C12H16F3NO5 and a molecular weight of 311.25 g/mol.
The molecular framework of (1S,4S,6R)-5-(tert-butoxycarbonyl)-7-(trifluoromethyl)-2-oxa-5-azabicyclo[4.1.0]Heptane-4-carboxylic acid (C12H16F3NO5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
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.
