Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(Diethylamino)ethyl 9H-fluorene-9-carboxylate (CAS 4425-78-9) is a high-purity analytical reference standard with the molecular formula C20H23NO2 and a molecular weight of 309.40 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-(Diethylamino)ethyl 9H-fluorene-9-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures 2-(Diethylamino)ethyl 9H-fluorene-9-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
