N2,N2,N2',N2'-Tetra([1,1'-biphenyl]-4-yl)-9,9'-spirobi[fluorene]-2,2'-diamine CAS 1174006-39-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N2,N2,N2',N2'-Tetra([1,1'-biphenyl]-4-yl)-9,9'-spirobi[fluorene]-2,2'-diamine.

N2,N2,N2',N2'-Tetra([1,1'-biphenyl]-4-yl)-9,9'-spirobi[fluorene]-2,2'-diamine (CAS 1174006-39-3) is a high-purity analytical reference standard with the molecular formula C73H50N2 and a molecular weight of 955.19 g/mol.

The molecular framework of N2,N2,N2',N2'-Tetra([1,1'-biphenyl]-4-yl)-9,9'-spirobi[fluorene]-2,2'-diamine (C73H50N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 N2,N2,N2',N2'-Tetra([1,1'-biphenyl]-4-yl)-9,9'-spirobi[fluorene]-2,2'-diamine 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.
