Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 337.24 g/mol gives (S)-2,2'-Bis(chloromethyl)-1,1'-binaphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (S)-2,2'-Bis(chloromethyl)-1,1'-binaphthalene (CAS 188780-03-2), a certified reference material (molecular formula C21H14Cl2, MW 337.24 g/mol) for analytical method development and quality control.
Owing to chlorine substitution, a polycyclic aromatic system, (S)-2,2'-Bis(chloromethyl)-1,1'-binaphthalene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 337.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (S)-2,2'-Bis(chloromethyl)-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.
