Chemical Structure
Description
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.
(1S,7S,8S)-2-(tert-butoxycarbonyl)-2-azabicyclo[5.1.0]Octane-8-carboxylic acid (CAS 1308650-44-3), molecular formula C13H21NO4 and molecular weight 255.31 g/mol, is a CATO reference standard with documented purity and traceability.
(1S,7S,8S)-2-(tert-butoxycarbonyl)-2-azabicyclo[5.1.0]Octane-8-carboxylic acid (C13H21NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
