Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 141.17 g/mol gives 1-Cyclopropyl-2-azetidinecarboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Cyclopropyl-2-azetidinecarboxylic acid (CAS 1042381-95-2), a certified reference material (molecular formula C7H11NO2, MW 141.17 g/mol) for analytical method development and quality control.
The molecular framework of 1-Cyclopropyl-2-azetidinecarboxylic acid (C7H11NO2) 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
