Chemical Structure
Description
3-Bromo-5,5-diphenyl-5H-dibenzo[b,d]silole (CAS 1154752-07-4), molecular formula C24H17BrSi and molecular weight 413.38 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Bromo-5,5-diphenyl-5H-dibenzo[b,d]silole (C24H17BrSi) contains bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 413.38 g/mol, it falls into the moderately-high-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 3-Bromo-5,5-diphenyl-5H-dibenzo[b,d]silole 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.
