Chemical Structure
Description
9-Oxo-3,7-diaza-bicyclo[3.3.1]nonane-3-carboxylic acid tert-butyl ester (CAS 227940-76-3) is a high-purity analytical reference standard with the molecular formula C12H20N2O3 and a molecular weight of 240.30 g/mol.
The molecular framework of 9-Oxo-3,7-diaza-bicyclo[3.3.1]nonane-3-carboxylic acid tert-butyl ester (C12H20N2O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 9-Oxo-3,7-diaza-bicyclo[3.3.1]nonane-3-carboxylic acid tert-butyl ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
