Chemical Structure
Description
As a certified reference material (CRM), 2-Chloro-9-(naphthalen-2-yl)-9-phenyl-9H-fluorene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-Chloro-9-(naphthalen-2-yl)-9-phenyl-9H-fluorene (CAS 2136614-37-2), molecular formula C29H19Cl and molecular weight 402.91 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Chloro-9-(naphthalen-2-yl)-9-phenyl-9H-fluorene (C29H19Cl) contains chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 402.91 g/mol, it falls into the moderately-high-molecular-weight range. 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.
