Chemical Structure
Description
The occurrence of 5'-Oxo-5'H,7'H-spiro[cyclopropane-1,8'-pyrano[4,3-b]pyridine]-2'-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5'-Oxo-5'H,7'H-spiro[cyclopropane-1,8'-pyrano[4,3-b]pyridine]-2'-carboxylic acid (CAS 2673370-52-8), a certified reference material (molecular formula C11H9NO4, MW 219.19 g/mol) for analytical method development and quality control.
The molecular framework of 5'-Oxo-5'H,7'H-spiro[cyclopropane-1,8'-pyrano[4,3-b]pyridine]-2'-carboxylic acid (C11H9NO4) 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.
