2-Chloro-5-phenyl-9,9'-spirobi[fluorene] CAS 2271227-64-4

Description

2-Chloro-5-phenyl-9,9'-spirobi[fluorene] (CAS 2271227-64-4), molecular formula C31H19Cl and molecular weight 426.94 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to chlorine substitution, a polycyclic aromatic system, 2-Chloro-5-phenyl-9,9'-spirobi[fluorene] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 426.94 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.

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 2-Chloro-5-phenyl-9,9'-spirobi[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.
