Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7,7'-Dimethyl[1,1'-binaphthalene]-2,2'-diamine.
7,7'-Dimethyl[1,1'-binaphthalene]-2,2'-diamine (CAS 756822-97-6) is a high-purity analytical reference standard with the molecular formula C22H20N2 and a molecular weight of 312.41 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 7,7'-Dimethyl[1,1'-binaphthalene]-2,2'-diamine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 312.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 7,7'-Dimethyl[1,1'-binaphthalene]-2,2'-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.
