Chemical Structure
Description
The occurrence of Rel-(1r,4r)-3'-oxo-3'H-spiro[cyclohexane-1,1'-furo[3,4-c]pyridine]-4-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Rel-(1r,4r)-3'-oxo-3'H-spiro[cyclohexane-1,1'-furo[3,4-c]pyridine]-4-carboxylic acid (CAS 328233-18-7), a certified reference material (molecular formula C13H13NO4, MW 247.25 g/mol) for analytical method development and quality control.
The molecular framework of Rel-(1r,4r)-3'-oxo-3'H-spiro[cyclohexane-1,1'-furo[3,4-c]pyridine]-4-carboxylic acid (C13H13NO4) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
