(S)-[1,1'-Binaphthalene]-4,4'-diamine CAS 18531-98-1

Description

The occurrence of (S)-[1,1'-Binaphthalene]-4,4'-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-[1,1'-Binaphthalene]-4,4'-diamine (CAS 18531-98-1) is a high-purity analytical reference standard with the molecular formula C20H16N2 and a molecular weight of 284.35 g/mol.

The molecular framework of (S)-[1,1'-Binaphthalene]-4,4'-diamine (C20H16N2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), (S)-[1,1'-Binaphthalene]-4,4'-diamine 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.
