Chemical Structure
Description
The occurrence of 2-Methyl-1,1'-binaphthalene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Methyl-1,1'-binaphthalene (CAS 69363-30-0), molecular formula C21H16 and molecular weight 268.35 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a polycyclic aromatic system, 2-Methyl-1,1'-binaphthalene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 268.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 2-Methyl-1,1'-binaphthalene 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.
