Description
CATO supplies 2'-Bromospiro[cyclopentane-1,9'-fluorene] (CAS 797056-47-4), a certified reference material (molecular formula C17H15Br, MW 299.21 g/mol) for analytical method development and quality control.
Structurally, 2'-Bromospiro[cyclopentane-1,9'-fluorene] (C17H15Br) contains bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 299.21 g/mol, it falls into the medium-molecular-weight range. 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.
CATO manufactures 2'-Bromospiro[cyclopentane-1,9'-fluorene] 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.
