CATO supplies Ethyl 4-aminospiro[cyclohex[3]ene-1,9'-fluorene]-3-carboxylate (CAS 6629-89-6), a certified reference material (molecular formula C16H16N2O5S, MW 348.37 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 4-aminospiro[cyclohex[3]ene-1,9'-fluorene]-3-carboxylate (C16H16N2O5S) is characterized by a flavonoid core, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
