Chemical Structure
Description
2-(((Octahydro-1H-4,7-methanoinden-5-yl)oxy)carbonyl)benzoic acid (C18H20O4) contains a flavonoid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
CATO supplies 2-(((Octahydro-1H-4,7-methanoinden-5-yl)oxy)carbonyl)benzoic acid (CAS 109821-56-9), a certified reference material (molecular formula C18H20O4, MW 300.35 g/mol) for analytical method development and quality control.
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.
