Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-2,2'-Diethynyl-1,1'-binaphthalene (CAS 426210-82-4), molecular formula C24H14 and molecular weight 302.37 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a polycyclic aromatic system, (S)-2,2'-Diethynyl-1,1'-binaphthalene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.37 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).
CATO manufactures (S)-2,2'-Diethynyl-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.
