Chemical Structure
Description
Owing to a polycyclic aromatic system, Benzo(B)Fluorene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 216.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies Benzo(B)Fluorene (CAS 243-17-4), a certified reference material (molecular formula C17H12, MW 216.28 g/mol) for analytical method development and quality control.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Benzo(B)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.
