Description
CATO manufactures 2-Iodo-9,9-diphenyl-9H-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.
CATO supplies 2-Iodo-9,9-diphenyl-9H-fluorene (CAS 768398-90-9), a certified reference material (molecular formula C25H17I, MW 444.31 g/mol) for analytical method development and quality control.
Owing to iodine substitution, a polycyclic aromatic system, 2-Iodo-9,9-diphenyl-9H-fluorene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 444.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
