1-(7-([9,9'-Bianthracen]-10-yl)-9,9-dimethyl-9H-fluoren-2-yl)pyrene CAS 1705571-70-5

Description

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 supplies 1-(7-([9,9'-Bianthracen]-10-yl)-9,9-dimethyl-9H-fluoren-2-yl)pyrene (CAS 1705571-70-5), a certified reference material (molecular formula C59H38, MW 746.93 g/mol) for analytical method development and quality control.

Structurally, 1-(7-([9,9'-Bianthracen]-10-yl)-9,9-dimethyl-9H-fluoren-2-yl)pyrene (C59H38) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 41.0, corresponding to approximately 41 ring(s) or double-bond equivalent(s). With a molecular weight of 746.93 g/mol, it falls into the 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
