Description
CATO manufactures Isopropyl 2,7-dibromospiro[fluorene-9,4'-piperidine]-1'-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.
Isopropyl 2,7-dibromospiro[fluorene-9,4'-piperidine]-1'-carboxylate (CAS 1804963-67-4) is a high-purity analytical reference standard with the molecular formula C21H21Br2NO2 and a molecular weight of 479.20 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Isopropyl 2,7-dibromospiro[fluorene-9,4'-piperidine]-1'-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 479.20 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
